Hi Laurent. Here's a version for you:
When you are writing an essay, always avoid short forms like "don't" or "shouldn't" - they are only for speech. I have changed a couple of phrases, but that is all. The changes are in CAPITALS or in [square brackets]
"« Forgive but not forget ». It is maybe possible to forgive something, because TO forgive is a decision, but TO forget is not.
IN my opinion, it is possible to forgive, even if it is something that a few people are able to do, but we CANNOT forget, because things are firmly rooted in our mind, and we CANNOT decide if [we want to get rid of our minds - NOT CLEAR, LAURENT - what are you trying to say here?]. INSTEAD, it depends on the seriousness of the act, because [we - DELETE THIS WORD] there are things we can forgive, and others we CANNOT. For example, how can someone forgive the genocide Nazis committed? On the other hand, if a little boy stole a candy FROM a confectioner's shop, it may be easier to forgive. Moreover, it is easier to forgive if the person who committed the act regrets what she had done because the pardon depends on the character of the victim and his readiness to forgive or ON the contrary HARBOUR A GRUDGE.
But when we manage to forgive, we must NOT forget. Should we forget the cruelty, the madness, the stupidity, the stubbornness of men? No ! Time is said to erase some wounds, but I think that time soothes some wounds. History lessons make us remember cruelty, madness... in such a way that we CANNOT forget. FINALLY, to forget is to BEHAVE as if nothing has happened, which is morally impossible for somebody who suffered a lot. For example, If someone LOST a close RELATIVE because he had been killed, it will be difficult for this person to forgive and forget because it will not be possible to BEHAVE as if nothing has happened.
To conclude, we should try to forgive, even if it IS hard but we must NOT forget because what happened before is an example of what we should NOT do."
