10 Worst Things Carnage Has Ever Done
8. Making Their Therapist Go Insane - Carnage: Mind Bomb
When the guy giving you therapy sessions starts to lose it because of you, you have to consider that perhaps the problems you have are a little more intense than the average bear.
Unfortunately for Cletus' misguided psychologist, Mister Kurtiz, Carnage's problems are on an entirely different level to ordinary people's, meaning their therapy session accidentally runs a little long - long enough that the chemicals preventing Kasady from using his symbiote powers wear off.
From here, it's the simple and awful case of Carnage drilling into their doctor's skull and showing him how the unstable villain sees the world - which naturally sends the psychiatrist sailing head-first into madness, unable to distinguish the symbiote's version of reality as separate from his own.
Kurtiz finishes this session by attacking the prison guards who let him in - naked, cannibalistic, and full of an intense inner rage - meaning that it's safe to say Carnage sabotaged the appointment well and truly.
