Pain killed Jiraiya because Jiraiya was considered an enemy to Akatsuki and an infiltrator to the Hidden Rain country. He knew some of the secret of Pain's God technique and was an enemy of his goals, sadly :(
pain
Yes He Does and Pain Akutsuki leader kills him
Jiriya dies by attempting to defeat all six pain at once,so his throat got destroyed by pain and he got periced six times by all six pain too (poor pervert.
first jiriya went under water and took the animal path under water into the stomach of a frog the jiriya used rasingan on it and then stabbed jirya and fell into acid

first of all orochimaru gets killed by sasuke in shippuden and during the fight between sasuke and itachi,orochimaru apears in sasukes body and itachi sealded him with his box that the sussano had and jiriya has a fight between one of the six pains and when jiriya thought he finish the six pain stab jiriya by a jump right in the back and tsunade she still lives
A direct quote from Jiriya: "I'm not a pervert......I'm a super pervert!" So, yes. He is a pervert.
