How can the House Rules Committee kill a bill even after it has been recommended by a committee?

The House Rules Committee determines when bills will be heard by the floor. Accordingly, if the Committee is against a particular bill, said bill won't be put on the calendar. So, in essence, the bill stays there until it is put on the calendar- which may be never. Furthermore, the Rules Committee could also have "closed rule" on the bill, meaning it will go to the floor, but it cannot be amended. Due to varying opinions, if a bill can't be modified on the House floor, it will ultimately die there.
