Most crime is due to needs.
Though some are because of the pleasure they are feeling whenever they kill someone. I do not know how killing someone become pleasurable but they are doing it wrong.
I would say that crime is a result of political failure.
It is, but not really providing education or job, it is way more than that. Some murderers seek truth it may be a revenge. The government can't answer that with things or education, they need to cure them using psychology.
Sure there are still rapists and murderers, there will always be a small percentage of mentally ill individuals that perpetrate these crimes. Killing them isn't going to do anything. What we should be doing is studying them and trying to figure out how to identify these people in their youth so that we can watch them and also maybe one day find a way to help them be normal.
We all know that that certain murderer will never be normal again, and I know you know that. People knows what he has done, as they say it, murderers will always be murderers even though that murderer is changing himself, people will always look at him as a murderer.
I don't disagree death penalty. Without it, these crminals will not fear anything even the government. We also have a lot of criminals that is so powerful they became untouchable, do you think studying will help them? No, they are a danger to other people. Yes, I know people can change, but it don't usually always work like that.
