I am completle agree with you, we need more way to deal with kids, to ex:
1. Some quests, where we can sacrifice them in rituals.
2. Some choices, where we can use them (Like use one of kids to lure owlbear from the cave)
3. Use kids as cannon fodder. They are useless anyway in fight, so why don't we move them to the frontlines, so the better troops will get more time to prepare.
4. I am certainly sure there is hidden option with that kid in druid temple and we can offer to execute little thief ourself.
Thanks, buddy, you have clever way of thinking.
