"I'm not going back! Don't even fucking try! Armin Tamzarian!"
"I am the guilt that surfaced after what you did to her."
"Kill the baby! Kill Maggie! Armin Tamzarian!"
Armin Tamzarian is possibly a Doif induced state, and not any single character, due to the connection with the Red Eyes.
A character in a Tamzarian state is also often depicted with the word "Vietnam" across their forehead. The implications of which are obvious in the case of Principal Skinner, but when depicted on other characters could be a blanket statement of guilt or fear or violence.
