to some extent, even though people say they relate to some things, i believe like maybe 50% of it. this is due to the fact that even though they understand how you feel, the experience in order to finally get it may be different from person to person which makes it very complex to actually put your feelings specifically into words.
Actually, my thoughts exactly. But, rather, my point is that they at least get to that point where they can say "I relate". Not gonna lie, I get to that point sometimes too but it's very scarcely so to speak. I hear/know some people can get to the point where at least they feel more motivated to keep going/living life when they see that there are thousands or hundreds of thousands feeling at least in similar ways. I never get to that point because I think there are several degrees of uniqueness in every person, and while some people are somewhat unique, others are like one out of a billion, and I feel I am there. So yes, that "I relate" may not be 100% but even 50% is a lot and even more if it happens a lot of the time and even more if it can motivate you/make you feel like you are part of the team. I know a lot of people get there, but also some of us never could I believe, because we are on other side of the uniqueness spectrum.
Honestly, I think your views pretty much hit the nail on the head when it comes to how the world is. People grow up with this black and white idea of good and bad. A lot of us like to forget that we are all humans and that humans are complex. Even the worst of us have a reason behind our behaviour, whether it be trauma, brain injuries or abnormalites, cultural upbringings, etc. We reduce people down to good or evil and through doing so we fail to recognize that even we ourselves are bad and evil, but we are also good too.
Along with that, those reactions you see people have when it comes to fiction are reactions that are reflected irl. When people see others who they interpret as the villian and those who they interpret as the victim they have the same reaction. However, at least amongst some people, that reaction ends when people remember that "villian" is also a person and that their reactions towards them have caused them harm. Even then, people don't want to view themselves as the bad guy, so they either double down on their behaviour or they pretend like they weren't a participant in causing that person so much pain.
I remember how I used to hold the same views most people did when it came to good and evil. When I was younger, it blinded me from my own horrible actions. When I got older, it caused me to feel like a monster when what I did finally hit me. Now, I'm trying to accept that fact that part of being human is hurting others, even when we don't realize it at the time, and that to grow means acknowledging those actions, learning from them, and using them to better myself. It's to use them as a lesson on what not to do.
Part of why abuse is a cycle is because victims starts to rationalize their own abusive behaviours and cannot acknowledge their bad actions since doing so means being a bad person. Part of why people commit heinous crimes is because they already view themselves as bad people and see no room for change. People who are bigoted will cannot see the harm they cause because they think of themselves as good people. You see yourself as the good guy because you are you. You understand yourself better than anyone, so it's hard to see how anyone from outsiders perspective can see you as a bad person. When you see yourself as bad, it's because you see yourself as a monster, so you don't see any point in trying to be good.
People are complex. You have more in common with the worst people out there than you do with Jesus or any of those 2-dimensional heroes you see in fiction. Everybody suffers to some degree. Like you said, we are all victims of this world. Acknowledging your complexity as humans and being able to acknowledge the good, the bad, everything in between that makes you you is important. To acknowledge that in others is important. When we acknowledge this, we allow for growth and understanding. A lot of the horrible things seens around the world, from cycles of abuse, normalized abusive behaviours, horrible prisons, crime, and more, partly stem from the black and white thinking we have been raised with.
Oh wow, there's so much I want to say here! First of all, and speaking of feeling related, I am happy someone shares at least a similar view to mine. I also like that you bring "brain injuries or abnormalities", as that's often skipped when talking about people's reasons for their behavior, and I think it actually has the same weight as pretty much every other possible reason. As there are physical, visible things that make our conditions different (height for example), there are also other physical things as well that makes us different and that motivate a lot of our behavior.
It's also interesting to me that you reached to this conclusion after going through a phase of pure "black and white" thinking, as I feel I've gone through something of the sort as well. Specially given I was raised in a very spiritual household (not exactly christian, but sort of), I mean, I think that played a huge role in my way of thinking for several years (and also in a lot of actions that I wouldn't do again now, but that I still sometimes feel sad about how people judge so toughly a lot of the time).
Regarding media and how those reactions are reflected irl, yeah, I always think that media is changing people's personalities. A lot of artists and creators say "We have to do it this way because the world has changed", but I have my doubts about that, as I think maybe because the media is following the trends, they are enforcing certain behaviors in people (our brains cannot properly distinguish between the outside world and the world of fiction, and if there's a chance of doing so, it is with a lot of awareness of what is actually going on when you are consuming media). In short, what I mean to say is that people are as they are partly because of media, and not the other way around. So that's why reactions seem to correlate very well, it's not just coincidence in other words.
"Part of being human is hurting others", curious because I reached that very same conclusion not long ago!
I also used to feel so crazy inside because I couldn't understand how I could have both good and bad traits in me, how I could be both a hero and a villain at the same time, but I think at least in that sense, a lot of us are in the same boat (though maybe lots of people haven't realized it yet, that part of why they feel like they feel is because they can't accept all sides of them). And yeah, that for sure must be at least part of why we see so much pain and suffering in the world. If you are labeled one way, there's no room for being another way, so it's pointless to try otherwise (under that logic).
EDIT: And I also think it's very interesting you say 'to how the world is', because that's my focus right now. I pretty much given up on 'being part of the team' and living the life that society expects me to, even though I work and have some hobbies but I don't do a lot of things that society expects of me, I am just trying to survive for whatever is left of my life now (after numerous and sort of miserably failed attempts if I say so myself).
