...Or, at least, that's what Evulz thinks until Bob lashes out and strikes back with conviction when he least expects it.
Bob's reply is "Are you finished yet?" and then proceeds to give a counter lecture to shut him up.
It's a borderline Curb-Stomp Battle in which the only blows Bob manages to land are sucker punches in the middle of Evulz's many and varied speeches.
When Evulz accuses Bob of being Not So Different from him, Bob misses the point and assumes that Evulz means that he, like Bob, is at heart a good person. Evulz is horrified by this implication.
Bob calmly mentions how he doesn't recall doing any evil deeds like what Evulz did nor does he recall Evulz doing anything heroic like Bob did. Bob then asks how are they similar again.
Zig Zagged: Bob dismisses Evulz's arguments, but is caught by surprise when Evulz has an answer for that. Bob refuses to give up and a pitched philosophical debate follows. However, things quickly deteriorate into a deadlock because both of them are using completely different value systems.
Averted: Evulz's arguments go unchallenged.
Enforced: "We can't let our hero be defeated by some jerk's attempts to deconstruct him. Bob's not gonna listen to that. You know what? Bob should just hit him!"
Lampshaded: "Ow, you interrupted my speech! Where is your heroic dignity?"
Invoked: "Go ahead. Tell me all the ways I'm wrong and why I shouldn't bother fighting you. I've always got time for some perverse rambling, but I'm gonna have to cut you off in a minute."
Exploited: Bob knows Evulz will try this, and manages to launch a sneak attack while Evulz is distracted making his lecture.
Evulz brushes aside Bob's attempt to shut him up and keeps talking until he's good and finished.
Bob doesn't bother letting Evulz talk at all.
Discussed: "I've seen this all the time. Once you get him making a speech at you, it's the perfect time to strike."
Conversed: "Why does Emperor Evulz even bother with the Hannibal Lecture? Bob's just gonna kick his ass anyway."
Deconstructed: Bob has a deep seated fear that he may be just like Evulz. Evulz tries to exploit that to psych him out and Bob devastates him beyond the usual fare of the work. Bob stops Evulz's speech but can imagine worse ones than Evulz could ever write and is haunted by them.
