I read somewhere someone saying that its their choice to commit suicide because its your life and not anyone else's. Committing suicide is a crime and If there's a victim who tried to commit but caught in the act, they should be jailed.
Not at all, and there is never any need to justify anything to anyone. Not much is well within our control in the earth plane, but we can decide on the time, manner and place of our deaths. That is within the realm of Free Will. Most chose not to exercise that choice because of idiotic reasons like the social control exercised by family, friends, government, religious zealots, and so on. To each his own. Suicide is a wholly viable alternative in many situations. That said, it is a serious option, and not to be engaged lightly, as there are ramifications both in Antarabhava, and in the next rebirth. Everything comes at a cost.
