“Aggressive, spiky button vs. rounded corner button”

That’s a very interesting idea. That kind of warning is usually conveyed by coloring the button red, but that’s often undesirable as it also makes the button more prominent (not so much in the case of a confirmation dialog like the example given, but in a more general context — like Gmail’s infamously unassuming Delete and Report Spam buttons).

Using more subtle yet instinctive cues to indicate that a button’s action has harmful results could work very well, especially in the iPad era. Think razor blades, urchins, etc.
