she's not evil, just traumatized and mentally ill.
christmas was the last time she was truly happy (see tree in pic rel) so she delusionally hangs on to it with every fibre of her being.
she keeps her AC on full blast and her skin as cold as possible because it reminds her of the winter weather and helps calm her down.
she hates rain because it breaks her "forever christmas" illusion and fucks with her head (this is why she forcibly shut the school down on a normal rainy day in the sweepstakes)
