For last few days I've read a lot of opinions on every possible ending of ep5 and really I don't want to start another thread about shooting Kenny or saving Jane.
All I want to tell you is that:
1) The concept of game since the very begining is about making tough choices, mostly very quicky and live with consequences.
2) EVERY ending is valid; EVERY ending has meaning and EVERY ending choice was made with your own emotions of the moment (love, compassion, anger, hatred, ...).
3) I also say, stick with your original choice. Telltale made something special here. Please respect everyone's choice cause it wasn't easy and that's what makes this game one of a kind.
TL:DR - We can keep arguing about ep5 final choices till season 3, but there's simply no need.
