Well, maybe at the end, but he was a christian when he did most of his research. Maybe it was the attitude of religionists of the time who caused him to become atheist...
You have not read his autobiography have you? Darwin plainly states he was not a Christian when he did his research.
Actually, their agenda was good science. You may be as paranoid as you want, but basically, science will forge ahead regardless of what fundamentalists think.
I am not paranoid and science will progress in knowledge and truth in spite of those who want to control the truth. As to their agenda:
Darwin's Hidden Agenda for Science.
There is no evidence in all of Charles Darwin's published correspondence and writings that he ever embraced biblical Christianity. As we have seen, virtually all the formative influences on his thinking were contrary to Christian faith. He always concealed his rejection of Christianity, but in his 1876 Autobiography he stated his unbelief in very blunt, even crude words. His closest scientific associates were all men who had given up biblical Christian faith, and some of them were committed enemies of the faith. For example, Sir Charles Lyell, the father of modern geology, was determined to discredit the biblical record of earth history, and Charles' "bulldog," anatomist T.H. Huxley, wrote that he was "sharpening [his] claws," ready to "disembowel" any clergymen who criticized Darwin's Origin of Species.

I suggest you do some reading and cease assuming you know what was in the minds of those men without reading what they actually wrote.
Ah well, that explains christian evolutionists, doesn't it? I have no problem with this. And no, the scientists you mentioned would not be YEC or IDist if they live today. Your sense of history is addled.
Have you read the personal letters and writings of the men I listed? If anyone's knowledge of history is addled it is those who make statements like yours without checking their facts.
