To be fair, the sycorax were running away, and Harriet Jones shot them in the back. The Silence had manipulated Humanity throughout time and had no qualms about it whatsoever. The Doctor just manipulated their manipulation.
Also, Humanity needs to succeed to preserve the integrity of any timeline, the Silence don't.

Well that's just good for establishing a difference between 10 and 11. Remember the 8th Doctor fought a Time War that killed millions. And the 4th attempted retroactive genocide on the Daleks.
I just didn't think that the Doctor should have done that, it's too far out of his character even taking into account the previous examples. The main difference is that if the Daleks had sued for peace the Doctor would have stopped, in all previous examples of him doing that he's never pushed harder than he's had to, even with the immediate example I think of (10 and Lumic) he never wanted to do it. This time the Doctor didn't set the trap and explain what would happen if they carried on, he just did it.
That's it actually, having thought on it it's that:
1. He manipulated innocent humans into killing without their knowledge.
2. He didn't give the Silence a chance to surrender, he just killed them all. In every previous example he's at least given them a chance but in these two episodes he
never offered a peaceful way out.
This wasn't even like it was a fixed point or that something needed to happen, he could have literally solved this however he'd wanted and the Doctor actively chose to slaughter tens of thousands. Even Davros got an out when he built the Reality Bomb.
