How do you write an explanation letter that you are guilty?

You didn't say this was personal or legal so I'm taking it as a fact it's personal. Be wary of putting anything in print unless you are guilty. Think about the problem for a week before deciding to write.It's best to talk to the person rather than having it in writing.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
