Dexter is not a violent person. He can assure you he will not troll or attack anyone with his linguistic skills. If you fear logic and psychology then Dexter might scare you. One may however be scared by extreme nature of such logic and psychology applied. It likens to 'going left to turn right' so to speak.

Dexter reccomends just being amused by him. He likens existence to a cosmic joke. Humor is it's nature and reality becomes a nightmare without it.
