I'd argue shooting oneself is going out of your way to shoot someone, that someone just happens to be themselves.

As to the aforementioned gang members, I'd argue that being a "good" or "bad" person and being liked don't always line up, as I referenced with the whole "crips have people who love them too" bit. Since being liked (or rather being disliked) is the prerequisite put forth, I'd argue that frankly most people fit into this category, regardless of gang affiliation. For instance, most people at work like me, but there are two or three that don't, yet the fact that 22/25 people like me means nothing if one of the 3/25 were to shoot me about it, but if one did does that mean I'm unlikable? No, it would edge toward meaning I'm "controversial," as in there is some controversy over the likability of me: Not all agree one way or the other.

As to the domestic violence, I'd say unequivocally that "yes, that is going out of one's way," frankly making the conscious decision on whether another human sees tomorrow is always "out of your way" short of self defense (during which the attacker could be said to put himself in your way). I'd also bet the one not beating the spouse is the one with a higher likability factor, but ya never know maybe the broad deserved it (kidding!) If the one being beat is the shooter it becomes self defense rather than a crime of passion, so that's out.

In any case, it seems frankly that the likability of an individual and being shot is correlation at most, not causation, and truthfully it's more coincidence than even correlation, being that almost every human has some people who like them and some who hate them, almost nobody is truly universally liked nor disliked.
