Why Criminals Get Executed

When someone commit a crime that is violent, there is a motive out of everything. For example, one criminal did the crime because of money and sex. Personally, I think it is unacceptable that there are motives after the crime they commit. I was shock when watching the documentary because it says in China someone can be sentence to death with fifty five crimes. My eyes was very stunned that someone would stab their ex-wife in public. I never knew people had so much courage especially in public to commit such crime. I just do not understand why criminals get interviewed before they get executed. I believe anything influences public opinion on a lot of things. It is not a shocking that such a show would influence public opinion on the death penalty
