It’s scary to see a mind trapped in an endless repetition of violent acts without meaning or resolution, only escalation to keep the stimulus going.

... the games of instantly rewarded destruction, in which the characters and action are ready-made “action figures” and the only goal is “winning,” are designed to be addictive, and therefore may be hard to outgrow or replace. Compelled into an endless, meaningless feedback loop, the imagination is starved and sterilized.

- Ursula K. Le Guin
