Quick search does suggest to me that a number of - even prominent - abolitionists were slave owners, but I'll be honest, the topic is hardly my specialty.
As for the other point, crazy, cynical, and even unethical as it may come off, it is hardly inconsistent with how people generally behave when met with hard limits (i.e. making the most of what's available, and approximating the desired state if that is unattainable). This is just a variation on the same.
Something could be said about "what if they're mistaken", but if all players are making a mistake, then that makes little practical difference; it may as well be real.
