求救!!英文翻譯請教各位高手 - 社會議題

I know many people support the death penalty. They say it stops serious crimes, like murder. They also say it's cheaper than keeping someone in prison all their life. Plus, they think that killers should have the death penalty - a life for a life. I agree with all this. But it would be terrible to kill the wrong person. Who can say this will never happen? There is always this chance. For me, this would be a worse crime. I think this is the most important thing of all.
我在奇摩翻譯字典和其他的翻譯網翻出來都怪怪的，都翻出字面意思，懇請大大的幫忙 急救>"<
