His backstory and long-brewing hatred for Mother Miranda give him different motivations than the other enemies, though not necessarily better morals.
Right after the first encounter with Ethan, while the player escapes from death traps, Heisenberg seems to be in control of the Lycans, which is even more commendable given that.

Powers and Abilities Karl is a brilliant engineer, being able to build a vast underground factory full of complicated technology for fast and efficient production of his cybernetic soldiers, however his genius mind is not without flaws, considering most of his creations, though inhumanly strong and durable, are rather cumbersome and have obvious weak spots, but the sheer scale of their manufacturing and intelligence some of them are capable to covering their weak points with their drills is impressive.
