I mentioned the Fixed Points, yes, which is a bullshit concept for him anyway. You'll also note that in NONE of those stories was he happy about doing that, nor did he go out of his way to make it happen with the express purpose of doing so. The dialogue here implies he KNEW about this outcome, and went along with their request just to facilitate it. Again, this is something the fucking Gallifreyans would do, and the Doctor has never willingly facilitated it unless he had no other choice.
It's also worth noting that, in canon, actual Fixed Points are relatively rare, and if the Doctor can avoid exterminating an enemy, he tends to do so. Just look at the Fourth. The dude literally spared THE ENTIRE DALEK RACE.
