I have to agree with both rinku di and LT, my sweets. Prithvi can never love Kripa as to the same extent as Angad loved Kripa or shall I say still loves her. He is hurt, he is pain, and that's why he is ignoring the fact that he still loves her.
This quote fits for Angad's love toward Kripa: "If I could only use one word to describe the way I feel about you, it wouldn't be love, because that would be a huge understatement." - Anonymous
Angad loves Kripa more that even I could imagine. It reflects through his eyes, his voice, his actions. He is hurt and he wants to hurt her back. He is using cheap language as his support source just to hurt Kripa back. I have to agree with Jink that since he has been brainwashed by his family, he sees no right or wrong. His actions my not be justified, but his pain is.
