Neatfires;
In Divinity 2 healing magic isn't holy, and undead are not inherently evil, so they are not incompatible.
In a world with levitation strong enough to keep huge rocks floating in the sky, I don't have a problem with levitation strong enough to control a fall. Also, the slayers were formed to exclusively go after opponents that can fly, so the ability to take a fall would have needed to be one of their first concerns.
Damian needed you alive, since you were the only possibility to get Patriarch to open a gateway to the Hall of Echoes.
Also, having the badguys immediately eliminate potential threats makes for very short games (and movies, etc) and violates union rules (
Evil Overlord List).

I can see wanting to prevent accidentally skipping a cutscene, but that could be prevented by requiring a double click / button press, or something.
