He doesn't cast people into hell they go there on there on their own because they has embraced falsities that prevent them from receiving grace.

Still immoral: even if someone directly wished to do themselves harm, the proper, humane thing to do is to stop them and get them help, not simply stand back with your hands in the air, all helpless, while they hurt themselves.
