How can Yash realy change so much? Cvs have changed or what?

I hate Yash like others. I think cvs have changed or at least some of d cvs. Yash was very nice guy. He was a true friend of Rosh who sacrificed his love as she loved only Sid. Later, he agreed to marry Sam n worked on his relation wid her. He forgave Sam for defaming him wid Kritika even if it tuk time. How can Yash really change so much. Post Bangkok n YaShni marriage track, Rajveer tried to manipulate him multiple times to join wid him to destroy Sid but he never agreed saying dat he won't anything wid wrong means. He gave a tough fight to Sid for Rosh but dat was only till he was convinced dat Rosh can be happy only wid Sid so he silently stepped back. Then how can he bcum negative all of a sudden? If he wanted then he cud have easily joined Rajveer na. Rajveer+Yash combo wud have easily been very tough for both Patels n Khuranas adding Kritika to them as she too was evil at dat time. Why all of a sudden he is blaming for snatching his Roshni 4m him n making him marry wid such a woman who cares for no one? I think cvs have changed n forgot wat was shown in earlier episodes. Instead of Yash, they cud shown Krish returning back or Rajveer's brother. Or even one of Chhabra's kids 4m his 4 wives wud have come for revenge.

Donno how much it is true but someone of Twitter said that creative head of JR is changed...but whatever it is changing yash to villain is to start a new track but it didn't work so they r ending it😆
