I am kind of amazed at how science is willing to do the most atrocious and heinous things to creatures and in some cases humans all in the name of science and of all things: helping humans. Unfortunately, I think without the bottomless rage of the oft self-righteous, Hitler's deeds would pail in comparison to what could be rationalized by the scientific community.
What? What science has ever been willing to, in your own words, "do the most atrocious and heinous things to creatures" in the name of science and helping humans? Are you referring to dissections? Vivisections? Lab experiments?
Let's see what Christianity has done, all without the interference of Jebus and the so called loving God:
The burning of pagan temples and destruction of various cultures by Christians during the Roman Empire's time.
Thousands of Hussites slain in the 15h century by Christians crusaders.
Other Crusades.
Spanish Inquisition.
20,000 Huguenots killed because Pope Pius V wanted them dead.
Gaspard de Coligny is torn apart, literally, his limbs severed along with his head and genitals then dumped repeatedly into a river and then fed to animals by Catholics.
The Troubles in Ireland where Catholics and Protestants came into conflict.
Jewish synagogues burnt down accompanied by massacres of Jews throughout Europe from the 4th century up through the year 1648 when 200,000 Jews were killed by Christians systematically in Poland.
Carried out mass genocides of the natives of Americas for country and God accompanied by the destruction of their cultures and ultimate conversion of the natives to the faith.
Witch hunts and fraud trials where dozens died.
Involvement in the Rwandan massacres.
The sexual abuse of children in various parts of the world.
Slave trading and the claim of slavery being what "God wanted" due to to a shit ton of verses in the Bible that approve of slavery (also formed one of the arguments made by the Southern states right before the U.S. Civil War)
Refusal to treat patients, who'd later die (some were children) medically in many cases instead resorting to "faith" and "healing".
Contributing to the white man's burden and imperialistic endeavors. (You can see the results in Nigeria nowadays where Muslims and Christians keep killing each other, thanks for that!).
Persecution of intellectuals, artists and so called "heretics" such as Galileo for being right about the Earth orbiting the Sun.
Fatal exorcisms carried out by idiotic priests.
A false sense of security in the face of danger (the Bible is NOT a magical force field generating book).
In some parts of the world, female "circumcision". Or rather genital mutilation.
Encouraging people to be as stupid and lazy as they can be (Creationism and so forth).
Not condoning the use of condoms (leading to the further dissemination of...AIDS! You guessed it!), other forms of birth control and demonizing abortion.
Convincing first class fanatics to carry out shootings in the name of their God.
Hundreds of years of misogyny and homophobia.
