Like MoiraV states in the reasoning, she used to psychology knowledge to bring out the "murderer" in people. So she made 3 people kill others.

In Spring Break Massacre, they find a Rorscach Test and investigate it, and learn that there were these same tests at the murder scenes of Murder on Campus and At The End Of The Rope.

Causing people to kill others counts as murdering them herself, so she was convicted of all 4.
