(Age of Wild Men) Was Gu Ma-jeok intimidated by Shin Ma-jeok? Or not?

‌
Every time Shin Ma-jeok caused trouble with Gu Ma-jeok's crew,
Gu Ma-jeok tried to reason with him instead of fighting.
Was this because he was intimidated by Shin Ma-jeok?
Or was it more of a "I'm not avoiding him because I'm scared, I'm avoiding him because he's not worth the trouble" attitude?
