He thinks like Robin and Slade. Morality-wise, he’s more Slade than Robin.

Brimstone was just about everything Slade could have hoped for when he first “recruited” Robin to his side. If anything, this clone outshined the boy wonder in many regards. And while his way of thinking often paralleled the leader of the Titans, there was an undeniable edge to the clone's mind that resembled his own.

He understood the path of crime he was created to walk on, and not once did he ever question his place in life or the purpose for his creation. He was an instrument of Slade’s will. However, he was not an unthinking tool: he had his own wants and desires.

But being so effectively raised by Slade left little doubt as to where his loyalties lie. Slade was his father, in nearly every way that it could ever mean. Brimstone was more than happy to see Slade’s will be done.
