Seeing the suicide couple reminded him of Kat and all the nights she told him to think of others more, so he decided to try and save Ben, but he locked Lee in the gate so Lee would still be able to save Clem if Kenny wasn't able to hold off the walkers. When he realized there was no way he could save Ben, he mercy killed him so he wouldn't have to go through any more pain. It was his way of trying to make things right and also make Kat proud of him.
That being said, I still like the Christa scene more. Especially when I picked the "Go back for him" option and Omid literally had to hold my Lee back from going down there.
Haha! I also heard if you save a bullet in the scene where you're going up into the attic, you can give him it and he'll shoot himself after shooting Ben.
