The difference is that hindus believed that if you were a bad person who does bad things you will be reincarnated into something in a lower class for example if your a farmer and you rob or kill if are reincarnated you can be reincarnated into a roach or anything that is worthless but if you have good karma you can be reincarnated into something even better.If you are a buddhism they believe that if you are a good person with non violence you will have good karma and if you're a bad person your karma is going to be bad and have to complete your eightfold path to reach nirvana.These belief systems have influenced our politics .and social aspect because people now and days still believe in karma that if you do good things u will get good things in return but if you do bad things bad things will come back to
