Below i'll post what i believe will be revealed in the future.
Loki will turn good, Harold will turn bad, Mosa is Shanks, end of chapter is Shanks's evil brother.
Loki was tricked by someone to be known as what he did was wrong. Harold's "peacefulness" was actually something bad as he wanted his villagers to embrace that thought at times of upcoming war. The event that scared Shanks was the future he saw related to Kid's attack while Loki said he would massacre everyone, not giving them a chance for revenge, as this was the second time Kid had a chance like this. End of chapter, Shanks-lookalike purposely not showing any of Shanks's characteristic identifiers (once again), being summoned by -as far as we know- Imu's powers, at the same time in which i theorize that Shanks talks with Loki.
