[How big of a change? Does Ezra even know? He's witnessed the after, but not the before - met Inquisitors and a Sith. Who even knows what Darth Vader used to be like, or any of the other Dark Side users Ezra's had to fight? All he has are Kanan's stories, words of caution passed down from Jedi to Jedi about people who Fell before. Ezra shrugs uncomfortably, because there's a difference between playing ignorant and being ignorant, and he doesn't much like the second one.

Briefly, he wonders how Maul would describe it. Formerly Sith, he'd called himself. Surely he'd know what it was like.]

They say if you give into it, you can turn against even the people you loved before. Your anger and fear and hatred can consume you until you don't remember feeling anything else.

[That has to be why Maul had encouraged him to try understand those feelings. If he understands them, then he can remain in control.]
