While I wouldn't stop you from playing as a pure War Boy if that's what you want I'd strongly recommend choosing a secondary role to help flavour the character.

For instance, if your War Boy was the type who'd be first to leap between moving vehicles they'd have Road Warrior as their secondary which would give a boost in vehicle combat.
If they really cared for their axes to the point where they maintained them themselves your character might have the Blackfinger secondary, giving them the knowledge to take [i]really[/i] good care of them.
On the other hand, if your character was a true master at carving up an opponent with their axes then Organic Mechanic as a secondary would let them butcher a target with feral precision, or just brutal bloodlust.

[quote=@GingerBoi123]Definitely Red for main but not sure on secondary. I was looking at green for the "sacrifice self for others" part but they oppose so I'm not sure on the rule for that[/quote]
You can choose any combination of motivations, but if they're opposed then it'll be difficult to collect enough points to break out the heroic moves unless your character prioritised one motivation over the other.

The better choice would be to consider why they'd be sacrificing himself. If they were doing it for glory, to be remembered or for selfish reasons then a Silver secondary would work. If they were doing it to provide the greatest good for others by their actions, or to make up for a perceived repayment for some previous wrong, then a Yellow secondary would be better. Either of these compliment the Red path and can easily be collected at the same time without conflict.

Than again some times a little conflict works well for a character.
