Hi @Baalekshan , This is expected as there can be cases where deletion of experiment will not handle stopping of chaos experiments. It will only delete Chaos Experiment but faults will still keep running. Actual solution would be abort the experiment before deletion.

We are closing this PR for now, feel free to open it!
