This is a pretty easy question to be answered: the MCU needs to stop killing its major players. For that matter, and quite surprisingly, the only superhero that hasn't killed his enemy from the solo film is the Hulk. That is right, the one superhero who is prone to destroying everything in his path is the one to let Abomination live.

On a different topic "“ is it that surprising, at this moment, that Superman killed Zod? It might be just a bit. However, looking into the MCU, where the superheroes have all the necessary experience, we cannot even frown at a simple broken neck.

We don't believe so "“ the MCU has already introduced some terrific villains, just to have them swiftly killed. We can only say that, so far, the Winter Soldier and (maybe) Loki haven't disappointed. In the latter case, the fans' reaction was the one that kept him in the MCU.
Maybe Marvel needs to change things and maybe they shouldn't be so trigger-happy.
