so im making a monk with 5thED rules and I want to follow bahamut, that said we have a CE tiefling in our party who plans on doing some rather evil things now my DM is worried ,as am I, that my character and his may have to do a death battle at some point. Now here the point of the matter the majority of our group supports the other guy more then me or the DM. Is there a way I can avoid having to fight him on this or changing my deity? he worships talona btw and wont change it again after we convinced him not to chose tiamat.
