We were absolutely no angels whatsoever, you only have to see the example you have provided, as well as our escapades in Ireland, to understand that. One of the National Curriculum's biggest errors in History is its near enough complete ignorance towards these types of situations. We do have a tendancy in this country to only highlight the good that we have done. While Churchill did an admirable job in WW2, his treatment towards the Irish in a similar period was far from rosy. You only have to see his suggestion to name a ship HMS Oliver Cromwell to see his thoughts on that matter.
I'm not one of these people who see this country as all seeing and all knowing. Does this mean I think we would have been better off in the present day had the Nazi's won WW2? Absolutely not. Comparing one crusade to another and asking which is worse is pointless as the contexts for every situation are totally different.
