My ex is bi-polar, and while she is completely nuts, she's not Mabus nuts. I can attest to the allure of the crazy phase as opposed to the not-so-crazy phase. Even just being in a relationship with her, and not myself being in that state of mind, it was something that I subconsciously sought after. The highs are fucking high, but god-dammit if the lows aren't lower than you can imagine.
Having said that, and reflecting on bi-polar persons (I tried to forget about it), it seems to be a cop-out excuse for his behavior. Although, I don't think "fucking nuts" is a clinical term.....
