yea im not crazy about that either. sure bring in Sinister and his obsession with Cyclops, but why would he want to "weaken" his favorite subject. his whole thing is to exploit his power.
No
Although sinister was obessive of finding or creating the ultimate mutant, his whole ethoes was not to Exploit mutant power...
Alot of people have a hugh misunderstanding of what Sinister is and does.
Dr.Nathaniel Essex saw mutation as something wonderful and beautifle, however he was not blessed with an ability. So through his experiments (Bearing in mind he comes from the early 19th centry) testing on mutants would of first started. Cruel perhaps but thats what science was back in that era. Now if you suddenly became immortal would your ethics of science change or would you try to keep things the way it was when you were less regulated?
Dr.Essex managed to find alot of things with mutant research and because of this he was able to make himself a Mutate. Human genome Alterd to mimic mutants dna.
Essex's Ethoes is this, Mutant is what evolution is, however humans are born non-mutant gene's are missing that ability and thats what he works towards, making everyone a mutant, well not making everyone but giving the option that anyone and everyone if they wanted could be a mutant.
BUT
Essex is a man of science, and if you read anything from the comics, cartoons...etc He doesnt like Genetic failer... the imperfect. His image of Mutation is that it leads to perfection within the species. When you get mutants that abilities are just dull, rubbish, serve no purpose. Then Essex judges them genetic freaks and he wants to rid the planet of that. "Which is what the Mutant Massicure was all about" again to anyone born in this century it woudl be unexceptable but Essex was born in victorian times and immortally his views has never changed.
Now what all this has to do with Cyclops is that, if you look into Gambits origin, Sinister helped gambit with his power because his mutant ability was too powerful, he couldnt not touch anything without it blowing up. So Sinister removed part of Gambits brain to allow him to be able to control his ability... thats what sinister does, but the way he does these things are soo unethical. Which is why he is a villian, but with his own vision... Just how Magneto is a villian but he has his own vision.
So when i see this with Cyclops and his burning lazer well look at it this way, you ask why would sinister dull down his power. He didnt, look at x-men 1 Cyclops blast is still powerful but no flames. He has perfected it... well almost.
