The death panalty penalty should be abolished

Today, I wanna would like to (sounds more formal) talk about why The the death panalty should be abolished.

I agree that the death panalty penalty should be abolished. (This sentence is fine, but a bit repetitive because you said the same thing in the previous sentence)

First of all, criminals also have a right to live. 
For example, the one,who kills other one, has a right as a human. Even though they chose their fate (by committing a crime), we don't have to make a discrimination should not discriminate. It's also unfair.

Secondly, people make mistakes and so it is possible that we could kill on an innocent person.
In 1989, there was a person who carryed out a execution was executed. A The police said "He was stealing and killing. but he didn't admit it until he was death." After 20 years, it ended up being a mistake of the police. What if there was no death panalty penalty at that time? We could have saved one life. We are same all human,. We make mistakes everyday.

For all the these reasons, I agree with this topic.
