Again - we're talking about Derek's motives here.

Isaac was a teaching method.

Stiles was out of annoyance.

Deaton was interrogation.

All of these are, for the most part, in character for Derek and he never tries to pretend he is anything other than a tough guy.

Theo's motivation for violence was to cover up a lie of apparently major proportions in the furtherance of a plan based on deception. It is so far out of character (the character he shows to Scott and Stiles) as to suggest a mental illness.
