5. He found a downed military supply plane full of weapons and is just having some fun.
My # were why he'd be pro-Legion, not to list the options of what he's doing.
Cause if it "was" that:
6. After the Legion his mind has been twisted and he believes all tribals are inferior and now makes tribes wage war against each other simply to make them eradicate themselves. Not for the Legion, but for his own delusion that they do not deserve life.
7. He is angered after what Caesar did to him and has taken it upon himself to create his own Legion in the "true" lords name.
8. After being treated by the tribe that he's now in charge of he took a liking upon them and has decided to help them to not get brutalized by the White Legs.
9. He now takes the word of the bible as a guideline of living and will force everyone to live under that rule, everyone who does not are sinners and need to be destroyed.
10. He simply loves war.
