Since Judaism, Christianity & Islam have all sprung from the same source texts, they all have the same degree of horrible ideas and are notionally equally bad. They are all like branches of the same Manchineel tree.
The main difference is that Muslims are the new kids on the block with the highest level of adherence to their faith, the Jews are mostly just "culturally jewish" not really following most of what is written in their books (with the exception of the jewish fundies in Israel).
The Christians have lost a lot of their steam, most barely knowing anything that is in their books.
Islam just happens to be in that crazy stage that all these other religions have already been through.
Islam will get ground down by reality just a surely as all the other religions will and have been.
But for today, right now, globally, they're doing the most damage to our species.
