Well, I'm not an atheist nor religious, the idea of karma comes from Hinduism which says good deeds will be rewarded and adverse actions will hit you back, meaning you won't get away with it.
In my short life, I have experienced few things were karma might act, I have seen those who got away with murder suffering from cancer and long sufferings. Also, I have heard of people who live happily ever after they committed homicide or rape.
So I thought about it yesterday for a few hours and conclude that karma must probably be a fancy word people use. After all, according to Hinduism the worst sin one perform is killing higher cast [ kind of racism in ancient Indian culture], and all their books are written so-called high-cast people maybe favoring their reign over the vast lower caste people.
what do you think?
Well I don't just believe, I can say that karma is BS and it's a fact. Why it is so, let me explain.
Suppose you have a cat at your home and you love her like a family member. One day when you are not at home, a dog attacks her and kills her. Then what you will think? Well, according to your perspective, that dog's karma was bad because it took one innocent's life and it should be punished. But on the other hand, when your cat kills other rats(taking one's life), then you will start justifying your pet. Because you love her. So the fact is that all happened due to food chain where one has to take others life to save his own life or just for fun or for anything else but we, human, named it good karma or bad karma.
Similarly, you like a fish and there was a bigger fish trying to kill it. You somehow managed to save that but when you have to feed that fish, ultimately you will take other's life.
Likewise if a lion is killing an animal, it's just a part of food chain and survival of the fittest. But when the same lion kills any human then our perspective will change and we will start saying that the person was killed due to his bad karma. There is nothing like karma and you can see that when you start considering this whole world as a jungle and we humans as a part of the jungle. As a lion kills a deer, similarly a man kills other one, is just because he is more powerful and same rule of survival of the fittest applies here as well. Being the wisest animal of this earth, we have created some terms like karma but that is BS.
So the only thing exists is perspective. There is nothing like karma in this universe. If you are a vegetarian, then you may say non-vegetarians that why are you killing innocent animals and taking one's life. And its correct according to your perspective. But at the same time a vegetarian is also taking one's life to save their life. Though plants have only 3 senses, but still they are living things. So again a non-vegetarian's perspective is also correct as you are no less than them. But again the fact is that it's all about the survival of the fittest. So if there is a murderer and living happy life and also if a terrorist kills other one, still there is no karma that will teach them a lesson. As a lion kills other animals then we won't say karma killed that animal, likewise it's not applicable to human as well. All we need to change is our perspective. Once you start thinking the whole world as a jungle then you will understand that karma is not a bitch, it's BS and only thing exists is perspective.
