Religion does not control people, people control people. People have done horrible things, not religion.
If you really want an example of oppression look to one name:
Pol Pot.
Who killed more in his own small country in the name of preserving atheism than died in either of those 2 secularly driven conflicts.
But let’s just look at the easy stuff: Human rights are more widely practiced in every country where religion (Christianity, Islam, etc) has spread. Almost every instance of slavery being brought to an end was done by religious activists.
Also, religion has given us culture, tradition, forms of art and music. Also, countless numbers of charities give money to less fortunate and organize institutions (St. Jude’s Hospital for example). People who affiliate themselves with some religions volunteer their time, some even leaving their home countries to help others. Is it 100% a good thing? No. has it caused issues like war or bigotry? Yes, but so have politics and government.
Many people will use whatever vehicle they can to serve their purpose. Religion is often used as this vehicle.
Guns don’t kill people, people kill people, remember this folks.
