yes and no.
Islam had killed hundreds of millions in its history. For instance the Delhi sultanate. Easily the largest genocidal regime of all time. Hundreds of millions of Hindus butchered over several centuries.
However I do believe it is on the rise compared to recent history. (say since mid 19th century).
So basically it has been much worse, but it seems worse now than it has been at times in the past.
