Brief an den Präsidenten der USA mit essay gegn todesstrafe

So, also morgen schreiben wir nen englisch test und müssend em Präsi der USa nen brief schreiben in dem wir sagen das wir gegn die todes strafe sind hier meiner bitte um korrektur da ich sau schlecht in englisch bin..:

Dear Mr.
President,

Today I am writing to you in order to tell you why the death penalty should be banned as a form of punishment. I think it’s barbaric to kill people who committed a crime and it’s also against the human rights. Our society has to move away from the “eye for an eye” mentality because I think we don’t live in the middle ages. I want to add that stay life long in prison is a worse punishment and is more deterrent for the people. You should also not forget that maybe persons who not committed a crime can be put to death. Also it’s totally useless and it doesn’t bring the victim back to life. On top of that it sends the wrong message to the people: why kill people who kill people to show that killing is wrong. On the other hand I can understand people who say that there can’t be any innocent men and women because today the DNA testings and other methods of modern crime scene science are at a very high level. Moreover I can understand that some people are like the death penalty. The death penalty might give a closure to the victim’s families who have suffered so much and people might argue that justice is better saved in that way.
Considering all these reasons against it, I think the death penalty should be banned as a capital punishment in the USA.
I hope you will ban the death penalty.
Yours respectfully,
