Change is something that we really can't control in life. It could be for the better or for the worse. And Scar changed to the worse here.

You are right, he made the choice, so people said mufasa made he become the scar we know him to be, but the truth is, he made the choice himself.

Scar killed Mufasa and tried to kill his nephew Simba too.

I imagine Scar committed these atrocities in the interest of self-preservation. Quite understandable considering that the wild can prove to be very chaotic.
