I disagree. Its the lack of fear of death is why we have so much crime now.
Except that's false. Capital punishment doesn't work as a deterrent; it never has*. There are plenty of countries where people are brutalized or executed for even trivial crimes but it has zero effect on crime rate.
There is also the problem of how arbitrarily the death penalty can be applied.* Depending on who you are, where you are from, the politics of the time, and the severity of the case. The death penalty is never consistently applied.
Another problem with the death penalty is that a lot of prosecutors pursue it, even on flimsy evidence, because successfully prosecuting a case which renders a death penalty is considered a prized possession among prosecutors. It looks good on a CV. You only have to look at how many people are exonerated to realize the death penalty is a dangerous game to play.
I see plenty of examples of people who do awful things which make my blood boil and my stomach churn; that is a normal, emotional response. However, the problems with capital punishment make me realize I am satisfied my country no longer practices it.
Just my 2 cents.
