@Kiraidesu: Yeah, based on the way he said his lines + his looks, he's basically that hard-boiled soldier taking care of a bunch of orphans or possibly even his own kids that and right now Leo is the one keeping their community together.
Leo likely plan to/want to fight Lufaas and Sagi here can't go against him since it'll break the community and put the children in danger again, so he can only play the 'bad guy' and give Libra the warning.
Because in some way Libra is 'stupid' and won't try to read deep into it.
In his mind he basically expect to be executed for becoming a traitor down the line, but also plan to do the whole 'the children committed no crime, so just let my death be the end of it, and also can you please take care of them' dying request.
Which given this series so far will definitely be denied and Lufaas will just use an elixir (this chapter mentions they have a lot after all) then tell him to look after them himself and not irresponsibly shove that to others.
