Question about Karma
If someone does us evil undeserved, that means we have got our karma back from god knows when.
First question: is bad past karma always the cause of such things?
And second, by doing us evil that person helped us burn our bad karma does that mean they actually did _good_? And if so will they get restitution for their deed or not, or will it rather be looked at as not that bad even though they didn't intentionally help us?
