I agree.

Because Harry's conscience pains him, he'll ask the 12 year old Draco to make a hugely life altering decision when he's in shock and hopeless about the future, and give him half an hour to do so, then hide that decision from him so that he can neither recant nor even know that he ever had such a choice, or made such a decision.

And how is that not manipulative or kinda a lie?!
