If the law of karma is real and the almighty himself promises to uphold righteousness then why still does evil and unrighteousness prosper so much?

The title is pretty self explanatory. If there is indeed a system of consequences then why do evil and bad people still roam happily and carefree in this world? People like Dawood Ibrahim still live their lives in comfort after causing so much destruction. So many evil people like rapists and serial murderers have gotten away and have lived their lives to the fullest before dying peacefully. Maybe an unknown example but Henry Kissinger,an undoubtedly evil man who caused so much death and destruction around the globe lived in full comfort and died peacefully. There are so many other examples,probably millions of them! Why didn't any of these people pay for their sins? Does it mean that the karmic system just doesen't work? I apologize but this has been going on about my mind for several years and i still haven't managed to wrap my head around it.
