Working with a monster

Can you imagine how you feel when you realize that the person you long considered a good person is a horrible beast

I could not believe how much my co-worker was a serial thug, uh, because I doubted him. When he was looking at me, the poor man was suffering from his mother, which formed a complex of misogyny, so he decided to kill them.

It's hard to believe that this successful and handsome person was a wild beast who invited me to the party today

And of course I plan to kill him and drink his blood to avenge all the ladies he killed
