Once fixing the defect regression testing is mandatory because defect impact other functionality or not once you tested.

In regression test, tester can ensure whether the previously passed test cases on modified sprint/software are passed this time also.., because those cases are related to previously failed case.
If regression test is not done after defect fixing, then that related cases may have defect and this may effect on next modified sprint.. the sprint/software after release may have so many defects and the quality does not remain.
