ELI5: Why does seeing something agressive or evil in a rorsharch test indicate mental illness?
gpt
Rorsach tests reveal the way you see the world. Such people see aggressiveness & evil even in benign things where no evil intent or aggression actually exists. 

People who see imagined aggression are often/always on the defensive, taking offense in the simplest situation or comment. Aggression is at least an action that can be observed. Seeing yourself as the victim of an endless world of aggressors never lets you rest, sleep well, or have any sense of peace. If mental illness isn't present already, it soon will be.

People who see imagined EVIL are taking a step beyond merely responding to actions & are attempting to read thoughts & intentions in others' even in places where no evil intent exists. While evil does exist in this world just as aggressive people exist, to see nefarious bogeymen in innocent & otherwise normal situations are doing themselves potentially irreparable mental harm. Again, no peace, no rest, high stress, etc.

Sadly, this can also indicate an inner battle inside their own mind between desire & control. The base desire is to lash out in aggressive behavior but thr conscious mind is struggling to act in a proper way. Similarly, the inner desire may be evil, but they are trying to hide it from others. As before, this inner turmoil can only go on so long until the mind snaps & settles on one of the 2 modes as the core integrity of a whole person. Either they accept the evil & act out on it in aggressive behavior, or they find Greater Power to purge the evil & aggression from within themselves & find the peace they seek. A split mind is irrational & a danger.
