Karna's (foster) mom was named Radha, that is why Karna is often called as Radheya (son of Radha), it is said Radha loved him over her own sons, but SPC showed that when Adhirath brought Karna home, she thought he is his(Adhirath's) illegitimate child whom Adhirath has brought home, so she started hating Karna, they showed her to be the evil stepmom, harassing him in every possible way. New way to victimize him.
Much later (probably post audience complaints), they brought a track, where Adhirath's life was in danger and a pre-adolescent Karna saved his life, post this Radha changed and started loving Karna over her own son.
Still I disliked the fact that they made this unconditional love of his adoptive mother into a love for reason and that too after making her an evil stepmom

As much as i hate Karna but this is unacceptable to show Radha like this..
