That's true. So does this mean that karma doesn't exist?

Karma is easy to refute if you think of it as a linear phenomenon, as in if you are kind to people, people will be kind to you. I don't think cause and effect works that way.

Example: your parents may have said if you get a uni degree, you'll get more job opportunities. That's the typical linear relationship, do A, get B. What's forgotten is the thousand things you did that can change the supposed outcome of A. You may have chosen a field of study that is no longer in demand. You may have chosen to party instead of studying and scraped through with a GPA of 2.1, causing your resume to persistently get shoved to the bottom of the pile. Sometimes even just being present at a place can change the outcome of A, as in someone comes to you and says hey, didn't we go to class together? My dad's the VP of the company you're interviewing at!

In all the scenarios, the common denominator is you, and the seemingly random choices you made prior to that point in time. You choose to attend a particular uni, the field of study, to party & skip classes. Every little choice - even the time you hesitated to cross the road and missed getting hit by a truck by 2 seconds, contributes to the final outcome. That's how complex cause and effect is.

So while the common variety "do A get B" definition of karma is a joke, the study of how a set of micro forces lead to an outcome is intriguing. It is as complex as predicting weather patterns, and can probably use the same concepts as the butterfly effect.

As I see it, it is for this reason that my reward for doing a good deed may not be the same as your reward for doing the same.

I see BE figuring in the parts involving measurable action like the accident example but you're right, I don't see where BE fits in when two people sit blindfolded and think bad intentions at each other. How do you measure intention anyway?

if there are such things as bad karma then should also have good karma, right?

That means you do good things and bad things will come to your later cause it's karma. Or does the mystique being on the universe know what is the difference between doing good and doing bad? Thus rewarding you for doing good and punishing you for doing bad (bad karma)?

That is why I'm always of the opinion that there is no such thing as good or bad, there's only consequence. Whether the consequence is perceived as "good" or "bad" is subjective, depending on which belief system you're from.

But things tend to go haywire, even if you do good things there's still a very high possibility you might get something bad in return
as in the case you helped a person but the person didn't feel thankful instead accused you of trying to take advantage of him or her 

not according to some bsdm video i see 

oops sorry
I thought karma only applies in the present life, i didn't know it can be extended to past life 

Here's a question to those who believe in karma.

If one does a good deed, and let's just say it's in a somewhat, huge proportion, i.e. donated a million to the poor, which side of karma (good / bad) that he will gain if the money which he donated were actually obtained through theft?

So does that mean as long as the person outweighs his bad deeds with good ones, "karma" will simply deemed his "bad deeds" as excusable?

Or, a more appropriate question will be, why is that bad deeds are always much more severe than good ones?

True, consequences may trigger separately in accordance to good and bad karma, but isn't it already a bad karma for a person to rest upon the relieve that he'll always be "okay" about it as long as he manages to top up some good deeds in compensate his bad ones?

For example: I stole something. And then I contemplate: "Hey wait, it's that bad karma? Oh wait, no worries. All I gotta do is to get some good karma, and all will be fine." AND SO I CONTINUED STEALING.

Now, I don't know about you, but that thinking is already a "bad karma". Karma may have consequences SEPARATELY for good and bad deeds as you put it, but to actually accept karma as a teaching? I personally think it will put us into that position where we can choose to justify our bad deeds with the good ones, and even if that's possible, I seriously think we're in a big deal of bad karma, which ultimately means that if you believe in karma, only bad things can happen to you, LOL.

Yeah, but that will put ourselves in the very position I described in my post.

But do you see the FLAW of believing in a thing called KARMA?
