I totally get what you mean.
The fact is that we don't know what there is after death. It doesn't matter what anyone says. WE.DON'T.KNOW.
I can say that punishing someone for eternity is not something that a loving God would do. Catholics are accused of making up hell to scare people into believing in their religion.
Many people are insane. Some claim this. Some claim that. So many religions. Some people "see" things. There is no way from a truly logical viewpoint to know if there's something after death or not. There really isn't. Maybe our souls do live on. Maybe the consciousness is energy that connects with the brain. Maybe not.
I have a gut feeling that there's something after death. I feel that religion isn't the case. It's probably more equivalent to the astral plane realm. But I could be completely wrong.
There's really no good answer on suicide. I guess that based on hell "maybe" existing,it's best to not ctb. But I just have to say that even if some form of Christianity is real,how would a loving,fair God justify torturing someone forever and ever for a single lifetime sin(sin from God's perspective). He made humans the way they are. He made the brains the way they are. Some people have messed up brains and do bad things. The brain can be injured and cause someone to become bitter or crazy. This means that the brain likely is responsible for personality,at least for the most part,rather than the spirit.(based on a religious spirit). So how could God punish a spirit for a human brain fault? If God did that,he'd be an idiotic asshole. Also,how is killing your human body so bad? It's a human body. Someone could go and kill thousands of people and suffer the same fate as you killing your own vessel? I mean come on? If God gets so hurt over a stupid Apple and killing a vessel(like destroying a car sort of),he needs to take a long look at himself.
So by logic,if God exists and is loving,he wouldn't allow any hell to exist. He'd be loving and teach us our wrongs. Not send you to hell to burn forever. Additionally,many things in the Bible are contradicting.
You may see people say that God's morality is pure and that's why we don't understand it. That's obviously bullshit that some Christian fanboy spat out to justify their God.
This is based on a religious God. Obviously there could be an evil God that punishes people. Anything is possible. But I wouldn't bet on it.
This is a long and logical answer.
I wish you well. If you ever need someone to chat with,I'm here for you.
