Killing Ruairi (Possible?)

In G3 segments, I wonder if killing Ruairi is possible if you avoid beating or playing it till you get strong enough to get demi god and the high end abilities.

In the paladin part of G2 he basically has limited hp meaning it should be possible to kill him and morgant in G3.

Speaking of which, I never finished my G3 for 2 years so if anyone with up to r1 shadow spirit and rage of wings would like to test this out, we could do a run in g3 and spam it on him (and morgant).

Morgant in G3 has the same stats as you fight him in G1, so he will die in a short time.

Ruairi has hax Def/Prot so killing him could be impossible.

Shadow spirit ignores defense and protection. Rage of wing's lingering damage ignores them too.
