Sarah is right.
Having seen psychosis first hand, the person that you know is often completely go at that time. My sister has had 2 psychotic episodes so far and both times her perception of reality was warped beyond recognition. She was not a violent psychotic at all. But in the first instance went from being a typical 19 year old that wouldn't leave the house without hair and make up done to one that didn't wash for weeks, walked outside barefoot so her feet were literally black. She insisted she was tinker bell, Cheryl Cole and Lady Gaga, which while it sounds amusing, to have a very sane girl suddenly truly believing this, while having completely lost the ability to care for themselves, is actually terrifying. She would walk out in her nightie at night and leave belongings on people's doorsteps. When she was sectioned and we found out about all this (she lived away) and went straight to see her, she was literally a shell.
The point of sharing this is that no-one can possibly EVER say what they would or wouldn't do is they had a psychotic episode. It completely takes control of you and your perceptions of normality, reality and right from wrong are completely warped.
Once my sister recovered, she was back to her normal self completely and cannot believe she ever said or did the things she did. It wasn't HER that behaved as she did, not the herr we know and love. It was the her in the grips of an illness that controlled her actions.
