Well yer paddies have always had a strange view of things, no doubt they have very subjective reasons to hate Cromwell but also they seem to have taken on his republican model. Conversly the paddies loved Hitler, assisted him where they could and even signed the book of condolence following his death. You see they hated the British fair enough but did they think old Adolf would give them a better deal should he conquer Britain? I don't think they really thought it through did they?
back to the Q though, how do you quantify "evil", Stalin, Hitler, etc certainly are responsible for a lot of deaths but they "knew" what they where doing was "necessary". So is it just most deaths = Evil or is there some other criteria?
