Yes it'd be great to "try", because if you're a dick you will kill beardless anyway, but try to diminuish KOS. ALSO when they implement weapon degradation, well, maybe it's better to save your hard earned M4 for a real beard-bearing man, right?
See, I got tired of trying to help out new players, on my first server it was very under-pop so I KNEW everoyne, unless they changed their name to gank me. But I'd help out newbies...tried it on my second server and they had a lot more players. I'd get shot in the face pointblank with a shotgun just to take the gun I was going to give them and maybe cloth armor. So I just started killing everyone on sight because fuck 'em.
