Analogy for why Canada needs to help Omar Khadr

Suppose you have underage nieces/nephews. Due to circumstances beyond anyone's control, their parents (i.e. your siblings) are unable to provide them with some necessity - food, shoes, education, dental work, something that children should reasonably be able to expect their guardians to provide. You are able to provide this necessity to these kids, and the amount of sacrifice required to do so is well within acceptable parameters. So you totally do it, unhesitatingly. There is no question.

Now suppose, instead of being due to circumstances beyond anyone's control, the inability to provide is a direct result of your siblings' actions. They've been total dickheads, done stuff that you think is not only idiotic but morally wrong and reflects poorly on all of you, completely fucked up so badly their reputation will never recover, and they've brought their kids into it and gotten them thinking these reprehensible actions are not only normal but laudable. And as a result of these actions, their children are lacking this necessity.

You still totally have to help the children. There's no question. Yeah, you might get a bit cranky about having to spend your hard-earned money just because your asshat sibling fucked up. Yeah, it's frustrating when the kids start spouting their parents' propoganda. But you have to at least give it a try, maybe use your influence to introduce the kids to other points of view and ways of life. You can always cut them off later if they prove as incorrigible as their parents. You certainly don't just ignore the fact that they're doing without school supplies just because you don't like their parents.

Similarly, we shouldn't be refusing to help Omar Khadr just because we don't like his parents or because he was in a situation that he was forced into by his parents.
