what i really understood about this topic after i did alot of research is that if you pour your bad intentions in a "way" that actually got manifested to physically/Psychologically harm the targeted individual you would get punished from a higher Unknown power .
Please Notice The Following
1- such anomaly take place if the targeted person is very pure
2- such anomaly take place if the targeted person is welding the right cause
3- such anomaly take place if the targeted person is being harmed with no reason
