Why do some people have this self destruct button in their psyche that they push any time they have something good going for themselves? Do you think they do it on purpose or is it some kind of mental disorder? To give a couple of examples...

Girl I went to school with managed to land a job with a fairly prestigious airliner as a stewardess after going to training, completing it (shockingly - this girl never completes anything) and spending a few months working for them... she just recently decided to skip going to work (i.e. leaving a flight short of stewarding staff and this isn't a Ryanair-esque company either...) in favour of taking pills and going to see a DJ and then spent the next day trying to guilt trip the people she went out with into staying another night because she'd been sent an email telling her she was fired and it was their fault she was fired.

Boy I'm friends with spends forever moaning about how single he is and how nothing good ever comes his way, starts dating someone who seems massively keen on him and then immediately self destructs by cheating with someone else on a night out and then blames his new partner for putting too much pressure on him.

Why do people do things like this? Why is their instinct to **** things up for themselves intentionally and then try and blame other people? I've only seen a handful of people like this in my lifetime but whenever I've come across them they're always at the extreme end, the kind of people that old saying about "a poor workman blames his tools" applies to.
