Don't know, never played it. Bloodlines is a good example of what I mentioned, except they never showed decapitations. Do a stealth kill with a ax in Bloodlines and it goes for the head/neck so I would guess that should have been a decaptiation.
I have been browsing various topics in the Kotor 2 fora and have seen "chat like" exchanges. The forum boards are not a chat room, lets not treat it like one. If you must talk, IMs and chat rooms work wonders.
