If Tekkadan uses children as soldiers, they'd have all kinds of child rights groups/organizations on their butts.
But if we go with the they're reborn, and children they induct are put in admin, engineering, IT, services (food, laundry, running deliveries on base/in ship, etc) to give them a leg up if they want to enter the workforce outside of Tekkadan, they'd probably be paving the way in human rights, especially if they also pay those kids in those fields.
I can see a hero version going on hunts for groups that use 'Human Debris' (orphans) or slave labour in general, possibly waging a private war against slavers, kidnappers, etc. Heck, they'd probably wage a private war against the First Order if they found out they abducted children and trained them to be soldiers.
Probably have running fire-fights with the Hutts as well when they're in the same areas.
