They saved the world from shit they started.
Loki was allowed to take over earth if he got the tesseract. This was not instigated by any of the Avengers.
Hydra took over SHEILD not because of any of the Avengers.
The Avengers did not create Ulton, Tony Stark did based off previous world ending encounters. He would have done so regardless because those events happened for reasons outside their input.
Vision's line is supremely stupid because conflict has and will always exist with or without the Avengers.
