You are pathetic and selfish for thinking that people should take those factors into consideration every time they see a player while they are deathmatching.
It's stupid that anyone should kill someone so soon after they've just spawned. It's idiotic.
How is it stupid or idiotic? It's a bit rude at most, but as I said, you can't take things like how long ago a player spawned into consideration when you're in a heated deathmatch. Most likely the player who killed him stumbled upon him and fired reflexively. Being killed shortly after spawning doesn't necessarily mean that there's some starfish spawn camper trying to make life hard for you. But please do explain why you think it's stupid or idiotic to fire at a player in a deathmatch.
