For me, I just am tired of Kate getting away with all her shenanigans, no repercussions whatsoever. She tried to murder Chloe,and not just once, drugged Sami to get her into bed with Brandon, so he would find them and cancel their wedding. She has cheated, seduced, manipulated, caused harm to so many, and never pays the piper. And while she used Theo to get info via computer, she should never, ever even suggested to him about breaking in. I don't buy her crocodile fake tears for a second, nor the declarations of loving either Theo or Chad like a son. Her sons have suffered a lot because of her, and where was she when Lucas really needed her, if just to be there?
The thing also is.....there are characters I would like to see gone, or at least back burnered, but murder means to think a bit. I am surprised about Stefan, since we have not even seen him yet, but I do understand not wanting another unknown Stefano son/daughter popping up out of the blue to "take charge". Eve has done it over at Basic Black, upsetting the Kiriakis family.....so this seems more of the same for the DiMeras.
But meanwhile, Kate truly needs to be brought down several pegs, and she is the only one I would WANT to see as a murder victim. Doubt she will be, tho.
