It is just to scare you... I have seen many 'bad' people, they never suffer
I mean people who would use others for benefit, corruption... making jokes on others and using all evil ways, cheating their bf/gf/hubby, they live for like 80 years and nothing happens to them!
I know one woman who did black magic to get a married man, she is beautiful and nothing wrong has happened to her! She is rich, has nice kids.. even after breaking a house nothing bad has happened to her so far...
I have seen people who work hard, pray a lot,study a lot, always toppers in everything, faithful n loyal, obedient, always do right and never harm another, they get killed in some accident at age of 20-30
Karma is only for those who believe in it!
Just do whatever makes you happy, you should go to bed without regrets :)
