Doctor Terrorist. Is it really that shocking?

They say that eight of the terrorists in the latest London debacle were doctors. Many people are shocked and dismayed at these news. I am not shocked. Dismayed, yes. Shocked, no. Though it's easy to think that all terrorists are cut from the same block, things are rarely that simply. Both history and literature teaches us that being a doctor does not necessarily equate being a healer. Hippocratic oath? More like hypocrisy. Just goes to show that intelligence and book learning does not replace wisdom and some good old fashioned common sense.
