In Agent Carter,
Howard Stark regrets his work making weapons, so much so that Fenhoff is able to use his pain over the Midnight Oil to hypnotize him.
However, in Ant-Man,
we learn that Howard is working in SHIELD, trying to convince Hank Pym to share his Pym particles with them,
and not five minutes into the first Iron Man,
we see Tony showcasing a powerful missile with all of the showmanship that one would expect from Robert Downey Jr.
Basically, my question is, why didn't Howard remember the lesson from Agent Carter? Or, if he did, how did the other two events I listed happen?
