When Peter later returned home, he was informed by a police officer that his beloved Uncle Ben had been killed by a burglar. Outraged, he donned his Spider-Man costume and captured the man only to realize to his horror that it was the same burglar whom he could have effortlessly captured earlier at the studio. As a result, Peter considered himself morally responsible for Ben's death and resolved to fight crime as a superhero — realizing that with great power comes great responsibility — and vowing never to let another innocent person come to harm if he could help it.
