No it was not. Instead of resorting to ad-hominem and calling people idiots, maybe you need to educate yourself about the meaning of the word "selfish".
Simply acting in your own self interest is not in and of itself selfish. Selfishness is specifically about doing so unreasonably, excessively, and generally with little or no concern for the negative impact it has on others. The word absolutely carries very strong negative connotations.
Yes, the OP certainly acted in his own self interest. But at no point was he unreasonable, or excessive, or without regard for how his actions might have affected others. The party who did act selfishly was the hunter and the raid leader.
Here's a source that explains the difference
And another source
As I pointed out in a previous post, selfishness is often described as being the
opposite of generosity. But some people confuse that with the absence of generosity. Not being generous doesn't mean that you're being selfish. It is entirely possible to be neither.
Absolutely nothing done by the OP fits the definition of the word selfish.
