You were hunting Amora with a group, and sang something offensive in a room full of halflings. Then never even stopped to bat an eyelash about it. From a character perspective I was amused. From a players perspective, you had just carelessly ended the lives of a handfull of good beings, and seemed not to give a damn. I didn't really have too many problems with you attacking evil people en masse' , but the halfling thing always bugged me.

Incidentally, I saw it happen another time, same circumstances, (I think it was Amora you were after that time too) and again you nuked a room full of halflings. This time someone else roleplayed some remorse and you did it too, but after what happened the first time I don't know if you would have done that on your own or not. But again, I had limited interaction with you, so I can't say for certain.
