I have to concur. These are essentially the same thing. The latter is arguably slightly less offensive because there's no less potential for it to seem mean, but they're very similar.
The main thing is, given the player is very new, if they weren't put off by the general reaction and sudden ending of the session, to make them feel okay about playing a character. If a new character will help with that, great. Some people will be put off by the effort of making a new one, though (yeah, I know a lot of us make characters like we breath, but my experience is that for newer people it's kind of a struggle).
They're a poor choice for the whole melodrama the OP planned, because they're new. An experienced player who did something murder-hobo-ish would have been a better target for such an attempt to "teach a lesson".
