different thesis statements for video game

The video game that i am writing about is called Assassins Creed

My first idea for a thesis is to write about vigilantism and how i believe that it is not morally or ethically wrong but it is a major controversy.

My second idea is to write about how ethically wrong it is to keep and treat someone as an experiment against their will.

My third idea is to write about how morally and ethically wrong it is to try and make and entire race believe in your own beliefs as the Christians did during the crusade.
