Peter could have facepalmed right then and there. She was admitting to robbing banks and it made him look so bad and he wanted to just toss himself over the side of the building right then and there.

"I do what I do to help people, because this city is a nightmare and even with people like Spoiler and Batman, it needs all the help it can get," he said as his explanation, "I don't want people to lose what I did." Okay, he didn't meant to say that but it sort of just slipped out and he felt like he might have just killed the chance to save this.
He shook his head, "Okay, we have two vigilantes and a thief. That'd make for a great joke but I'm drawing blanks right now."
