So it basically means their character in Noah's view is not worth it. They did not plot against him (good for them!), but he only earned ridicule, contempt and scorn (for making monsters stronger). They wanted him to die - so he won't heal or support them. But I believe he won't go against them either. Bit like Batman when he says: "I can choose not to save you".
Is this not partially doing the same thing as them? They had no respect for you, so they didn't help you. Now you've got no respect for them so you're not going to heal them. Noah would be failing his own test right now if one of the others pulled it on him. Only Amber and the other two would pass. Realistically it might only be the couple that pass as they hadn't had any prior thoughts about him
