I don't believe in Past Karma at all.
I only believe present karma, which means you do bad, you face bad consequences.

There's no point punishing a new life with what he did in so-called "previous life"

I don't know about other religion. In Chinese, generally, have this "bridge" where people drinks a soup (some soup that you will forget past life after drinking it) cross over the bridge and reborn. Supposely all the sins are being wiped/forgive and so.

Even for a criminal in this present life, mostly what we said is "He will go to Hell" But in Chinese, we using the same terms, they went to hell and have their punishment there, but when they are allowed to be reborn, supposely again, their sin should be wiped/forgive already.

So there's no such PAST KARMA at all.

Well, that's my POV. Different people, different belief.

What i mean is past life's karma.

Sorry for the misunderstanding.

Highlighted again for the SAKE of the so-called GOD.
