can chinchillas be evil?

I am not gonna lie, the temperaments of the chinchillas vary from one to another, in my life like a breeder i have seen all kind of temperaments, some chins super sweet and calm, and other very mean and active. does the fact of interaction with the chinchilla will affect their behavior? yes. Definitely it will, but it can be in positive way or negative as well.  i had a chinchilla that i start holding it on my hands everyday, she was very active, you barely could get a hold on her, but after insisting so many times she became more calm and nice to me, until one day that i accidentally dropped it (somehow really hard to explain). i was told that chinchillas have great memory and is true, this chin since this accident, she won't let me hold her no more, actually, she did turn kind of evil, when i get my hand in the cage she make these noise of try and you'll see, than she pee on me, yep, this is a female and females have the habitability of spray liquids to their predators...  

yep, she looks so mean, actually she is...
but she gave me the sweetest guy in my herd...
