Very much a spoiler if you haven't seen it yet

I was there on that fateful day, were you?
Naruto tends to kill characters off for no reason for dramatic effect.
Keep watching and it'll make sense... or not...
As an aside the whole dying against Pain is stupid. It looks to me if Jiraiya took like 5 guys as good as Kakashi they could've taken care of Pain easily once he figures out he comes back from life after killed. The Pains by themselves are pretty weak except the head guy so just say put Jiraiya on the leader Pain, 5 other guys can easily take out one of the Pain 1 by 1, and after you kill them enough times you'd be able to figure out how to get them to stay dead, and Jiraiya + 2 guys like Kakashi would be able to take out the leader Pain easy. I guess ninjas aren't known for strategy since they always insist on fighting 3 Pains at once even when they got enough personnel to split them up.
