Jmeter cleanup/ force not to abort before completely executing a group

I have a jmeter script with 1 group containing 5 requests. I need this script to run forever and will kill it manually. the problem comes when i kill it manually but it has completed only two reuest and 3-5 are not done.

eg: i am performing CRUD test. So it has created resurce ,read the resurce and I terminated script or timed script got terminated automatically. The delete will not execute and it leaves extra entry in my database. How do I prevent it?
