Kartik does not hate Survi
He loves her very much
He is just hurt & angry because Survi left him despite him having said to her " Mein Tere Bina jee nahin paunga " & about Lata
He is trying to find answers as to why Survi did what he thinks she did to Lata although she loved him & his mother way too much
Kartik's love for Survi 8 years ago was strictly platonic though as opposed to Survi who fell in love with him
Maybe now Kartik is starting to have romantic feelings for her
About Shrikant he has to be horrified right because what Aniket did was plain horrific
But then again Kartik admires & loves Shrikant a lot.He owes his life to Shrikant.After all Shrikant made him give up the life of crime
Woh dream shayad sirf Survi dekh rahi thi,I think.That girl fell in love with Kartik 8 years ago & Tai knows it.Even Vishakha realised it.& that's what made it easy for Tai to blackmail Survi into leaving giving her,her pyaar ka vaasta
