Reading comprehension is important, seems like it might be difficult for you but if you read that sentence closely it said "if you can".
Character consistency is important in stories go figure. 😮
If you've read this story up until this point you might have realized that Rimuru's long term goal is coexistence, he doesn't have a full grasp on the situation so instead of flying off the handle (now that he's regained his composure at least) he realized that haphazardly killing these people can result in a much bigger issue (since he knows Hinata is somehow involved).
