No, we're not. The momment an individual becomes dangerous to society, the momment a life of a person may harm the life in society, this person needs to be taken out. Humans, above some age, never learn, They don't acknowledge their mistake. It's very hard to change a person's mind. So, if he can't be fixed, he should be locked forever. If that isn't working, he needs to be killed. It's simple as that."Grrr! I'm so upset that he killed someone, which is wrong, I want him to be killed!"
The dude's scum yeah, but all you guys saying stuff like "I want him to be killed/beaten/rape" are being real shitty.
This moralism of yours, always causing more problems than fixing it.
