In my first playthrough i regret:
- not being too nice to Larry
- smashing Larry's head in (infront of Clem)
- being so bad to Ben, i just realized he's still a kid (kinda) if it was too late
- pitchforking that guy (in front of Clem)
- taking the supplies
- not having the option to hold Danny back from shooting Jolene
- letting Clem talk to that Radio >.< on the other hand i couldn't tell her, that her
parents were probably dead straight in the face.
- not feeling too much on Carleys death/ not being able to avoid it
- I couldn't protect Duck
- telling Katjaa about the meat locker, i felt like it was my bad she killed herself
- not being nice to Chuck
- accidently shooting Molly
- getting bitten, and not being able to protect my girl
- saying: i need that walkie talkie, when it fell down there, i thought it was my mistake
Kenny died
- letting Ben drop in the belltower
- not having the option to say "sorry i forgot your b-day girl" in the Marsh House
- killing the Campman, he didn't deserve it... but payback's a bitch

- not teaching Clem more than i did
- not being able to tell Clem "i love you..." or something like that
- making her cry...
- telling her to shoot me
- having her seen more then she oughta
- more stuff I'll edit the post as soon as I know more things to regret.
