Common misconception: The SWs are just as ruthless as normal Space Marines. Difference between them is that, if the SW deem you an ally (Like the people of Armageddon who fought tooth and nail, whether they were in the Steel Legion or not) then they will not let you get killed and they will defend you as if you were part of their Chapter. If not, then they won't give a rats ass about you...unless a higher up tells them to kill all civilians. Because SWs do not take orders from non SWs :3

Now the Salamanders, on the other hand, those are the good guys of 40k.
