Roger was not responsible for Syd having a mental breakdown. Roger was not responsible for Syd doing too many drugs and worsening his mental state. Roger was not responsible for the band as a whole deciding that they needed to move forward without Syd, owing to his increased inability to work.

There are more than enough things to legitimately blame Roger and his ego/attitude for, without making things up. Syd was not well. Exactly how unwell he was and to what degree he was unwell we'll probably never know, but trying to say that it is not true or that he was a victim of Roger's dastardly ego is not going to change the fact that he was in fact, a sick man.

So yeah, I'd say your post was wildly inaccurate.
