Why do people come into the wilderness and complain when they get pked?

Like why do you come into the wilderness (which is part of the game) and then get pissed and complain to people when they kill you? You chose to come into the wilderness. I'm just enjoying this portion of content in the game. This happens quite often. Just recently I was flamed by some guy who told me to kill myself because I pked him (for decent loot actually). Monk robe boy, it's not my problem you choose to come into the wilderness and don't want to get d hides for 15k and learn to pray switch and not die. Get good kid. If not then gg sit back to lumby goblin boy. Not sorry. (No I don't actually spam stuff like this in-game).
