It happens on a regular basis around abortion clinics (the latest victim was Dr Tiller just a few years ago).
I am tempted to say that the horrors that Mother Teresa inflicted in her clinics would also qualify as terrorism, but that's probably more open to interpretation (well, the horrors are not open to interpretation, whether it should be called terrorism can arguably be).
Have you never heard of the IRA or Basque separatists? These days most terrorists in the US & EU are protestants, but the Catholics have not given up their attempt to wrest first place from these upstart prods...
The Catholic Church does not endorse murdering entire populations, including children, newborns and cattle. In fact, it is in no uncertain terms completely opposed to such things.
I asked you about the Catholic Church and you tell me about the Bible. You are free to argue that the Catholic Church is hypocritical and misinterpreting the Bible when they condemn murder, but that wasn't the question.
