I think I remember Feige saying in an interview that he noticed fans' reactions or feelings about the villains and he said that they were going to try and change the villains in future movies. So, yes I think they did decide to let some villains live. Plus fans are hoping for teams like Masters of Evil and Sinister Six, which would require villains living.

But there are also theories that Red Skull and Ultron survived.
