Exactly. I think I know how the scene could be.
We see my Spider-Man with Tarantula after an intense fight with some thieves, Spidey would realize that Tarantula is very violent when he fights, and see how Tarantula almost killed a thief and Spidey would stop him, Tarantula would be angry with him and Spidey would tell him, “We don’t kill thieves, we shouldn’t kill anyone”, to which Tarantula would reply, “Well, if we shouldn’t kill them, we have to make them suffer, they hurt many people daily and you just let them live.”
Spidey tells him: “I know what you go through, you’re young, you still don’t understand how to work on this”
Tarantula says: “Shut your damn mouth, I really know how to work on this! The one who doesn’t know anything is you.” “I just want them to stop killing people”
Spidey: “But you kill them, you become one of them”
Spidey: “These powers were given for a reason, you can’t go around killing people, you have a responsibility.”
Tarantula: “A responsibility? What are you talking about?”
Spidey: “Sigh”, “Ben Parker, he was the one who told me about responsibility, he was my uncle”
Spidey: “He died because of me, I ran away from my house because of a fight, he followed me, I already had my powers and I knew he wasn’t going to find me”
Spidey: “He ran into a killer, Cletus Kasady. Kasady just stabbed him in the stomach which bled him out, when I found him, there was nothing I could do to save him.”
Spidey: “I don’t know how, but he found out he had powers, and his last words were, With Great Power Comes Great Responsibility.”
Spidey: “So don’t be like I was, your loved ones could die from one of those mistakes.”
