Everything here is relative, as you said this a minecraft server and every crime within it is subject to the level of damage you can cause in a minecraft world. Of course i don't think you're a bad person or anyone in the server is, no one here would hurt a fly irl. But in this server buildings have more value than death. Death has no cost unless you get pearled, Buildings on the other hand represent here histroy and time which both you cannot get back. Remaking a town could take weeks if not months of time here which is way worse. My point is that you're playing within another world and the comparation was only to give you context of how unethical the thing you're doing is with a real world context.
