Much of what Doom gains is ego rather than strategic, though it did neuter alot of his enemies.
But the Life Force is such an ass-pull I incline to think it's just a shell-name for something else.
Ian McNee makes no bones about it in Marvel Tarot; it's one or both of Wanda's two primary enemies, the Elder Gods Chthon and Set.
Chthon loves to play cruel games with Wanda, and that in itself would be motive enough for him. The most ridiculous moment in Secret Empire was that Tony Stark never asked him "Oh, Chthon, been meaning to ask you, where were you during that M Day stuff that happened, were you on vacation with your buddy Sagbata or something?"
The two weirdest things about House of M are the total absence of Vision {whom Wanda would definitely put in her reality} and Chthon, who absolutely would show up and start playing around, because it's just too damned fun for him to ignore.
If you are talking about who would have the strongest motive to specificly manipulate Wanda into "no more mutants" , the strongest candidate is without question Set. Why Set? Because Arishem the Judge snubbed his Serpent Men and favoured humans by giving humans the x-gene, effectively siding with his hated sister, Gaea. The very existence of mutants is an affront to Set, and wiping out almost all of them would be a massive "up yours" to the Celestials, effectively flushing all their carefully laid schemes down the toilet.
Set would surely be laughing his ass off and relishing the humiliation of the Celestials, in his eyes, this would be payback for what was done to the Serpent Men.
