I wouldn’t be a Christian

[Belacqua]

So............ the good ideas/words of christianity out way the bad. 

I'm sure a lot of people believe that. 

I have no idea how they can quantify the good and the bad in order to make that assessment. As you know, in the real world of power and violence, theological disputes are never pure. They are always mixed with economic and political issues. For example:

Um........... kill them all and let god sort it out. (yeah I know, not accurate) But it was said, by a christian, for the purpose of killing, people were killed (lots of people).

This atrocity was committed while the Catholics were fighting the Cathars. The argument began as a theological dispute, but it became more than that when Catholic noblemen were told they could keep the lands of Cathar-supporting noblemen whom they defeated. Suddenly a lot of indifferent Catholics signed up to fight. 

When the guy said, "Kill them. For the Lord knows those that are his own," chances are he was also thinking, "and I don't care because the guy who pays me gets to keep the real estate." 

Confirmation bias is a real danger here.
