Who started this narrative that Draco Malfoy was forced to join voldemort?

Everywhere I see people saying Draco didn't want to be a deatheater. He was forced in it.

But I remember at the end of book 4, this kid mocked Cedric's death and gleefully told Harry, scum like Hermione would be the next victim of voldemort and after that it would be harry.

Bellatrix told Snape, Draco was excited that he was chosen for such an important task by the dark lord himself. He himself said to lackeys on train that he wanted to make dark lord proud. He even refused Snape's help because he thought Snape wanted to steal his glory.

It's only when his all plans failed to murder dumbledore, he started to panic because now dark lord was gonna kill him and his parents. Still no remorse for his actions that he almost killed two people. Even in the bathroom when harry saw him crying his 1st instinct was to throw a cruciatus curse at harry.

Literally where did people get from that he joined voldemort while kicking and screaming, against his will?

Also when did he get redeemed or become good? His last act was begging a deatheater he was on their side after harry saved his life.
