However, Scarlet Witch would eventually bring an amnesiac Clint Barton back to life in a new parallel world she created in a story called House of M. She ended up killing him again after his memories returned and tried to assassinate her, but she still did him a solid by resurrecting him when she set the world back to normal (minus most of the mutants).
Hawkeye died in an attack from a Kree invasion, which ended up being created by an insane Scarlet Witch.
In 2005, several Avengers were killed in a storyline called Avengers: Disassembled.
