And why should this bother the EvilDom at all? After all, if you don't impose some fictitious standards on his personality, which currently exist only in the minds of individual players, then in essence, this is the path of maximum selfishness, a willingness to walk over people, betray them, sacrifice them, friends, and sometimes even kill the people. And all for the sake of gaining power.
So in the context of the EvilDom, your argument about collars simply doesn't work. This route is not at all the path of Robin Hood, and certainly not the path of some kind of “righteous avenger.” So don't kid yourself. You play as a person who, through your efforts, is rapidly turning into the same evil sadist as the people around him.
