Say you're a pirate. Can you successfully swash-buckle without being a murderer?

Avast! Ye swab, if ye want to swash-buckle, ye must tie 'em to the yardarm, forty lashes, matey. Ye must be ready to lop off the head, me bucko! Ye must keel-haul 'em and then to a watery grave and Davey Jones Locker, arrrh! Ye must be feared among the seven seas!
