And of course, they would rather blame the child in question than take responsibility.

It's an example of the theme we have of children being treated like adults, really. They're always fully to blame for anything bad they do, and it's totally okay to expose them to sexual stuff. It's disgusting and awful.

It was quite evil of that duke, since draining that lake would have meant killing all the life in it (not to mention the negative impact on its enviroment), it trapped Zeherah in the Ichtar ring and it means that Sigholt loses its natural moat

Sorry, but this is REALLY reaching. He did it because the stupid fucking bridge literally wouldn't let him enter his home. Like what the hell else was he supposed to do? And he wouldn't have known about Zeherah to begin with.

But as you say, even if this was the evillist thing ever, his descendants had nothing to do with it.

Plus the so-called "heroes" in this thing do every evil thing in the book (literally) yet draining a lake and killing someone you honestly believe is pure evil is painted as crossing the line? Are you fucking kidding?

I also cannot help but wonder if the Icarii being white plays a role...

Given how racist this series is, it's absolutely a factor. She won't stop pissing on about it, either.

because it is about Drago's "redemption"

Which is bullshit because Drago didn't do anything. He isn't DragonStar. DragonStar was wiped out of existence as a baby. And even then, what DragonStar did was full of what you'd call mitigating circumstances. He should NEVER have been expected to shoulder all the blame like that.
