I Have An Unpopular Opinion

I'm not sure how (un)popular this opinion actually is, but here it goes:
I think bullies whose actions eventually lead to the suicide of their victims should be put into jail for a lifetime.
The process of bullying is basically stabbing someone's soul/sanity more and more until it's hardly bearable for the victim anymore so that they think suicide is the only option.
I wonder why people even think it's fun mentally killing people just because they don't like them the way they are...
