Another douchey DM action: during the fight the Barbarian activated his Rage power (things weren't going that well, just more ammo to prove that the battle WASN'T one-sided on our favor). The DM decided that unknowingly he killed the good villager (that was with us) and found out at the end. Pretty sure by RAW, Barbarian Rage gives him strength, doesn't make him berserk. One thing I don't like about this group, is that they use a heavy houserule of 2e, and a lot of things are waved off as "well, it *would* make sense that if you're raged you can kill random people". I don't have anything about rules interpretations or not doing everything "by the book" but when opinions like "it makes sense" just get turned into implicit rules that result in pretty heavy handed bad stuff for the players.
I mean it "would make sense" that if you slipped and fell backwards you could crack your skull and die instantly. But that's not how rpg's work... if in a specific game you have HP then you have HP and if some specific things instakill then it's very important to make sure what these are and that there's a damn good reason to throw at the players. You're not going to kill D&D players because it makes sense that any "medieval" setting has bad hygiene and every person has a 0.2% daily chance of randomly catching dysentery or whatever and die, and there was no "cure disease" available at the moment.
It's like the whole Paladin argument. It's bad enough that RAW causes no end to arguments between people who said they should fall if they kill an innocent that was transmogrified into a deadly hobgoblin (but at least atoning is free in this case, he can be a Paladin again next week, Hurray!), and people who say "the rules only say willingly". Then you start adding things that "make sense" like "it makes sense that the Paladin is a subordinate of any cleric of his same deity and if he commands him to do bad stuff he falls if he disobeys and he falls if he does it" (this actually came up in conversation in my group). But the rules don't say that Clerics are the bosses of Paladins, and the fiction doesn't support it either (if you take for example, Jean D'arc as a paladin... Paladins are pretty much loose cannons, and they think they have a direct and righteous connection to their deity and can even consider Clerics to be failing their vocation if they aren't as fanatical as them, even if they're both roleplaying their classes correctly. It arguably makes just as much sense to have Paladins and Clerics bickering all the time because Paladins think Clerics are DOIN IT WRONG and vice versa!).
