When Pudge was in his old school he riding have any friends and when he was having a go- away celebration, nobody came. This affected his behavior in the new school because he didn't know how to act and easily fell into peer pressure. Also, he was new to the school and didn't know anything, or who to hang out with and the Colonel and Alaska guided him. This shows that he had to do what he was told because they were the only help that he got. His backgound wasn't the only factor of why he was irresponsible.
I think that he was insecure, this was also a factor in Alaska's death. The Colonel and Alaska always were partying or pranking and Pudge didn't exactly know how to act around that. If Pudge wasn't so insecure he could have stood up to the Colonel and Alaska and told them to stop when Alaska got into the car drunk. Also, Pudge followed the Colonel and was never the leader. If the Colonel was doing a prank then Pudge was always dragged into it too. When Alaska wanted to go into the car drunk, she needed a distaction/ prank so the Eagle wouldn't stop her. The Colonel said ok so Pudge followed him.
All in all, Pudge's situation at school and before affected a lot of his behavior at school with the Colonel and Alaska. If Pudge had a different background than Alaska might not have been killed because of Pudge's bad judgement and irresponsibility with his friends. Because Pudge was the main character we got to know his background; but the Colonel made bad mistakes too. I wonder what caused him to be so irresponsible.
