10 Worst Things Tony Stark Has Ever Done

MCU Ultron is an interesting case as, although it was easily one of the worst things Tony has ever done, it’s not like he created Ultron to be a psychopathic, misanthropic, mechanical monster on purpose.

Still, as far as mistakes go, Ultron is comfortably among the most terrible things Stark is responsible for (and Banner too, although people seem to always forget that fact). The Ultron Offensive killed innumerable people (over 150 at the battle of Sokovia alone), and brought humanity to the absolute brink of extinction.

The devastation Ultron caused, in addition to Tony’s own guilt for his hand in the matter, were also huge influences on the events that led to the MCU’s Civil War as well. Whether by intention or not, the creation of Ultron left a lot of blood on Tony’s hands.
