As IEFBR14 is a frontend to SVC 99 (allocation), SVC 13 (abend) is the frontend to RTM. It's a way to stop things in their tracks when fubar is detected.
In an online program (either cics or vtam) it is a good way to begin to attempt recovery when storage corruption or resource usage out of range is detected. In a batch stream if a file allocation fails, recovery usually requires intervention by carbon-based recovery routines. We have a program whose sole purpose is to abend when a non-zero rc is detected, usually after IDCAMS. Another use for an abend is to fail a job when recovery-by-waiting exceeds a predetermined limit. We use this to cover for failures by the automation system to react to "rules" in a timely manner.
