I think breaking it is justified if you give the nominal warning. I mean NAPs are all fine and well, but if you wind up NAPed into a corner what are you going to do? Personally (even though I don't do much MP) if you want these kinds of NAPs you should play with team mates and treat everything else as temporary.

The question seems to be do you want to try to win. If you don't, then pick who you want to win and just help them win, playing spoiler is all fine and well, but realize at the same time that you're usually only helping someone else along the way, so as long as you're ok with that its all good.
