Worf claimed the overthrow of the military leadership on Cardassia was simply an excuse that "has given my people a chance what they were born to do - to fight."
Orkses iz made fur fightin' an' winnin'.
Klingons just dress it up a bit more, at least the higher-ups. Remember Kurn trying to convince Worf to relax and enjoy himself during the Klingon Civil War? A hall of feasting and drinking warriors, all of whom likely tried to kill each other earlier that day, having fun singing and headbutting each other?
Yeah, i guess they would be a match made in Sto'Vo'Kor
