Compared to other games in the series like VI and VII, V is one of the lightest entries in the series. Which isn't to say that it doesn't have dark moments, but everyone in FFVI goes through something comparable to what Galuf goes through: Mog becomes literally the last member of his species; Cyan watches his entire family die; Terra is literally enslaved and forced to murder upwards of fifty people just for Kefka's kicks; and the list goes on.
