Worst decision you can/did make in a game?

[Dulfite]

I wanted my brother to play Zelda A Link to the Past on the SNES when I was really little (back then I enjoyed watching others play more than playing myself). He didn't oblige me, so I deleted his save file. I still to this day feel bad about that. I'm 27, about to be 28 and he is 30 now lol.
