The answer is, what happens beyond life and what your punishment will be: NO MAN KNOWS.
we are not even sure if people are sent to punishment right after death. all we do know is that in the end of days, at the final judgement, you will be judged according to your deeds.
if you still feel justified in your suicide, i don't think you have much hope.
from what i've read, you're only sent to hell when the world comes to an end, but i haven't read everything.
