Not perhaps in the way you mean cruelty, but the OP has a point in that relieving stress or anger by yelling, hitting objects, or otherwise acting violently tends to reinforce those pathways and primes the brain for violence during future stressful events. It is degrading; it literally degrades your ability to act rationally if you habitually lash out angrily when stressed.
