Although I was kind of expecting this scene…since the mangake's previous work planetes was all about love and peace..
Thorfinn's parting of violence seems too soon or out of place, and especially the meaning of Warrior..
He should go back to his home, to sea his mother and sister though,
anyway It is not hard to picture that despite Thorfinn proclaiming that he will part with violence... he still have lot of fight left to do in this manga.
Snake and the king and his adventure...
