Everyone hates Sam but loves Tory??

So I just finished the first 5 seasons of cobra Kai and for me, I thought “well, I want to see how many people hate Tory” and to my surprise, everyone loves her?? They all defend her actions by saying “well her mom died infront of her” and that she’s had a hard life. No doubt, but everyone made fun of Sam and said she was a bully and annoying for having trauma from getting sliced up in SCHOOL by a random girl. And people take it even further by calling the ACTRESS Fat???
