Do you agree that "the ends justify the means"?

This is the kind of concept a utilitarian would agree on. If the result is positive for a large group of people, we should seriously consider doing it.

However, I would like to comment on this concept. In my opinion (and that's what you're asking for) there are situations in which the ends don't justify the means. You can e.g. think about mass-bombings to fight against terrorism. However, the possibility exists that innocent people will be hit, and will die. Therefore, the end don't always justify the means (in my opinion).
