You know, it's weird, I just realized all the bad shit that happened in Age of Ultron can actually be attributed to 3 Avengers.
Iron Man/Tony Stark,
Hulk/Bruce Banner,
and Scarlet Witch/Wanda Maximoff.
Tony Created the weapons that blew up Wanda's home, giving her a hateboner for Tony Stark, meanwhile Bruce Banner tests out risky treatments for super-soldier powers on himself, accidentally creating the Hulk. Later, Wanda chooses to go to HYDRA to give her a chance to get back at Stark, and uses those powers to freak him out about space, so he'll do something stupid, which he proceeds to do in spectacular fashion, enlisting, again, Bruce Banner, to help him create an AI from a rod he knows barely anything about, which backfires, and the murderbot goes back to work Scarlet Witch, who again, is so consumed by her revenge-bent that she works with a clearly suspicious 10 foot tall killing machine, and teams up with him, to later screw with Hulk's head, who then proceeds to destroy Johannesburg, with, to a degree, the help of Tony Stark, who is attempting to subdue the Hulk. When she switches sides, and it all goes airborne in Sokovia due to the monster robot that the the three of them created, Wanda's own brother gets shot down by said robot in a Tony-Stark-tricked-out quinjet.
Pretty much everyone else is completely blameless in this.
