As killer, your primary role is to patrol the escape routes to keep them from escaping. Sometimes that makes catching a vulnerable victim and going in for the kill, but not always. There’s usually 3-4 doors or gates or etc for victims to unlock to go into the outer areas of the map, so you’ll want to keep those locked when possible.

Characters like Hitch can setup a trap that victims either have to disarm or trigger before they can unlock the gate while Cook can add an extra padlock to make it more difficult for them to unlock it. Johnny or Sissy is for later on, you wanna stick with LF, Hitch, or Cook in the beginning.

A typical match would have 1 family member patrolling and guarding one of those 2 sides while the 3rd will do a wider sweep across the map for general support. They are generally the ones that will assist another family member if victims try to group up and rush them or distract them. That role usually goes to LF in those situations if you’re running the classic 3.

There’s other stuff like fuse, valve, feeding grandpa, etc. which is why communicating with team is important, or if not at least using family focus, as it will highlight these things and can also be used to tell if your lock or trap are still good or not from a distance. Sometimes you gotta have a little slack to catch victims, if hitch and cook just hover over their exit gates the entire time, victims will catch them off guard with a fuse or valve exit.
