To novel readers

I think they attack them because they're near the forest where dead mana swamp is and also redika is a crazy mage.

Yes it is. It's actually just been revealed in the most recently translated chapters (650+).

Though, it technically hasn't been confirmed, but it is implied that the reason why WS attacked the village was because he sensed the ancient power while he was gathering dead mana for the mermaids in the Forest of Darkness. It has been confirmed that he is capable of sensing ancient powers and only OG!Cale knew about the ancient power being there.

The bastard likely wanted to cover what he was doing up, gain more dead mana, and such, and killed the entire village whilst retrieving it. So two birds with one stone? Not entirely sure, but I think my theory lines up with his psychotic character.

As for before chapter 200, I can't quite recall. My guess is he either wanted to continue getting the dead mana (which I've forgotten whether it was dealt with at that point or not) or wanted to do some payback/weaken on Cale since that's where part of his force/family resides.

And yeah, another reason is because Redika is crazy

Thank you very much and to the others as well unfortunately i will not be reading the other comments as I’m only on chapter 250(￣∇￣")

Good choice. You don't want to spoil the surprise xD
