It wasn't just "idiot who cares more about his reputation of a loyal knight than the actual wellbeing of his nation and also, not to put too fine a point on it, the safety of his beloved sister"

I mean he's still very much that but it's not as much of the Camus problem as it first appears... not after you meet his son Ares

And Ares manages to fulfill all the actual ideals of chivalry and righteousness that Eldigan failed to

...because Eldigan died long before he could actually teach his son the corrupted, fossilized version of what "chivalry" had become in Jugdral

It's amazing how many different ways FE4 created children who idolized their deeply flawed parents and the different directions they went in

Arion managing to completely blunder off the path that Travant tried to lay out for him

Seliph's mentors, who loved his father, nevertheless doing their best to steer Seliph away from the choices that led Sigurd to dig his own grave

Bloom becoming even more of a selfish, craven jerk than his father Reptor was

Leif trying to avenge and/or live up to Quan and Ethlyn even though his advisors are much more open about the ways those two screwed up

Nanna diving even harder into incest kink than her mom did

ANYWAY IT'S SOME REAL GOOD SHIT
