You completely ignored the positive influence of Christianity upon medical care and schooling, the founding of universities and hospitals, the positive influence upon philosophy and political thought and Human Rights, the role it played in ending infanticide and human sacrifice, etc.. .
Romans outlawed human sacrifice about 100 BC. Today's modern medical symbol (caduceus: two serpents entwined around a winged staff) stems from pagan God Hermes... Hippocrates (460-371 BC) was a Greek philosopher-physician who has been called 'the father of medicine'. He and his followers dismissed the idea that illness was simply caused or cured by superstitions, spirits or gods. Greco-Roman society were into universities [The Platonic Academy, est. by Plato: 387] thus four centuries before Christianity even became a gnat on the radar screen.
NONE of which negates the positive role of Christianity upon the history and formation of Western Civilization.

Jesus Himself called on followers to act without violence or prejudice and care for the sick, hungry and poor. Throughout its looong history...*many centuries*...Christianity (using Jesus’ teachings) has positivity influenced Western Civilization in the ways mentioned above, and more.
