Okay? so?? someone killing stray kittens could be a plot device, should I not say that's twisted and wrong of the character? (Not to mention this is a lazy and almost useless plot point)
Also, one of the core things of engaging in media and stories is analysing and criticising the plot, characters, themes, motivations etc? Have YOU read anything in your life? or maybe you just turn your brain and critical thinking off when you do.

They're both immature and selfish, don't involve other people in your drama. I knew not to date people I don't like at age 11, wtf are you doing using other people and agreeing to date someone just to cheat on them? Sorry but escapism isn't a good enough excuse.
