Well, if you're fighting some injustice, in some sense having more of it happen is "good", because it will make make your cause more public, and so has a better chance of reducing it in the future. These "warriors", as you refer to them, most likely don't wish for more violence, but also recognize that something good can come out of it. This doesn't mean you should become cynical or suspicious of the cause, it's just how the publicity game is played. If you're far removed from the subject, it probably comes off as calculating and cold, but in reality it probably also feels very bad for the "warriors".
