Compassion=Love
Depise=Hate
So, to gain in Compassion, one must show love and to lose Compassion one must do a hateful act. What I mean by define is, what that would be. So, any act that is kind would be a gain in Compassion.
And any act of Hate would be a gain in Despise or a loss of Compassion such as murder or war. So, you would have to build an understanding.
An example would be: If something is good, like a Unicorn or has positive karma then it would be love and anything with negative karma would be hate. So, if a Red killed a Red, they would gain in Hate and if a Blue killed a Red, they would gain in Compassion. So, it's not really defined.
As you take each Virtue and explore their opposites, you find that they are not really opposite of each other but different, where one is negative and the other is positive.
Like, if somebody would steal an item, then the opposite would be to give someone an item. So, it's easy to say, Give and Take Away but when you use words like Love and Hate, you begin to generalize emotion to the extreme of Yes and No. So, you have to explain or define why. So, what you basically have is alot of work in figuring out how a system would recognize the difference between the 2.
So, it could become a moral issue. I ask myself, Why do people kill animals to eat them if there are other sources of food and when someone kills an animal because they are starving and need to eat, Do we consider it murder?
So, then you have to ask, Is every killing a bad thing or is every War a bad thing? So, now you begin to have trouble actually defining what is good and bad and if you look at this System of Life, you realize that these systems are necessary. For example: Day and Night, Love and Hate.
If the system lacked in one of them then you would not be able to build an understanding of either of them and if you only have the negative, then the system would destroy itself.
