My sister is emotionally abusive and bully and his husband cheated on her? Is it Karma? Does she deserve it?

My sister is not very nice person. She is emotionally abusive and bully to us. She always treats me like shit always make fun of my body and face. Calls me names like stupid. Always Humiliate me in front of other people and even calling me annoying and stupid on her post on her social media. Always wish me to be sick whenver she got sick like she wants to heal and pass her sickness to me instead. "I hope youd rather get sick instead of me" " I hope my flu passed on you so I get healed" and her hubby cheated on her and she's sad and crying do you think she deserve it? Is it karma?
