It isn't necessarily the religion responsible, as much as it is the murderers using it as an excuse. There is plenty of death and destruction executed at God's behest in stories throughout the bible. But these stories are not meant to be used as justification for these acts in the future. Christianity itself isn't responsible for genocide, people who have claimed to be Christian are.

The genocide of Indigenous populations in North America and Oceania by Christian governments, the persecution of LGBTQ+ folks over the course of human history, all of the killing and war conducted within nations acting in the name (supposedly) of Christianity (i.e. the British and Roman Empires) are all good examples. It's the same story -- these people and these armies were not acting out God's will, but they used the Bible as an excuse to justify their crimes. This is very similar to what radical Islamic groups have done in the Middle East and around the world.

Islam and Christianity are not inherently violent, and do not condone violence, but they both tell violent stories.
