"He abandoned Harry and he was jealous when Harry's name got out of the Goblet of Fire!"

he was 14 did you never screw up at 14

"He abandoned Harry in the woods!"

he was frustated and he was under the influence of the Horcrux and he immediately wanted to go back but he couldn't

sorry that he wasn't perfect i'm sure you never did anything wrong in your life ever and you were never angry at someone that didn't deserve it
