The way I see it, some people play DayZ just for the thrill of the kill- they are interested in the combat and not much else. This is probably why so many private hives spawn you with a weapon/ increase vehicle frequency/ etc., because that lets people get into what I see as the meat and potatoes of the game mechanics: realistic combat. Yes, the element of paranoia and fear that the zeds bring early game is nice, and I enjoy banding together with survivors, but in a game that places so much more emphasis on noncombative actions like scavenging as compared to say Battlefield or Call of Duty the real satisfaction comes from killing (and getting killed by) other players. In ArmA II, there are very realistic ballistics, weather effects that affect the player, realistic injuries like broken bones and bleeding, a procedural loot system, large open worlds, persistent characters, etc. almost all of which is lauded by the community as that which makes DayZ great. However, the fact that one or two bullets from most guns kills (and the weakest guns still only take four or five) is often lamented especially with relation to sniping. Sniping is not without its perks. It is a quick, efficient relatively easy way to kill someone without having to worry about messy engagements. It rewards you steeply for landing a hit and punishes you heavily for missing. There are many players who appreciate the high-risk high-reward mechanics of sniping, and that is why they do it. But is taking out an unarmed or uninterested player who literally does nothing to hurt you or notice your presence unethical? Yes. However, DayZ is a game that seems to bring out a large gray area in its players in the form of banditry. In my eyes, it is no more unfair to snipe somebody than to shoot them point-blank and loot their corpse. It does however seem unfair from the perspective of the victim as they have apparently been struck down by God himself. So, in summation sniping is not a bad thing, nor is banditry. You're always going to get bandits and those who desire some quick adrenaline and those who desire a more realistic survival experience are always going to come into conflict with bandits, regardless of anything the devs really do. TL;DR: Bandits will be bandits
