If Clem shot Lee,it would give her some closure but she would have to live with a fact that she killed one of the most important persons in her life.And it might make her stronger,unless it makes her weaker (it definatly wasn't easy for her to shoot Lee)

On the other hand,if Clem left Lee...she will always think about what happened to him but she won't have think about how she killed somebody she loved alot...also,she will keep the bullet if she ever needs it to save herself.

Now,both choices are not actually good but i left Lee,and this is why : she already killed walkers but killing somebody as important for her as Lee is totally different (atleast that's how i thought)...and i also thought this is the last thing Lee could've done for her...to save her from having to do something as horrible as that...

Anyway : people have different opinions...
