Generally? Yeah. But you most likely felt wronged and wanted revenge... because something big probably happened--something that can't be undone no matter what.

[ That's why Oria is more understanding about it rather than a "omg emil dont kill people thats bad". Also, he has definitely seen Sinclair angry, but to imagine something worse than that... that really would be destructive like Sinclair said. Man. ]

It's a human emotion. It's normal.
