I'm not too sure on this one. I don't think the people left behind by suicide necessarily hate the individual who took that option. I would be more inclined to say that they are extremely hurt, just absolutely gutted that someone they care about found life that difficult, that reprehensible or that they were in that much pain that they decided to end their own life.
They no doubt go through a whole sequence of feelings; shock, anger, pain, remorse and, let's be honest, an extreme sense of guilt. They'll likely ask themselves why? Why hadn't they noticed? Could have they done something to stop it, to help you find the will to survive and so on?
Also, you've got to consider the fact that a lot of people find suicide really difficult to get their head around because, just like anyone else, they possess a strong survival instinct. So, to know that someone they care about felt things were that bad that they could override those billions of years of evolution is confusing. That probably adds to the already intense cocktail of emotions they're confronted with.
That said, I'm sure there are instances of people who genuinely do feel hatred for someone who ctb. In those circumstances, I'm not sure what could drive someone to feel such a powerfully negative emotion for someone who just decided that their quality of life was no longer acceptable, at least not to them.
