Meaning, morality

The only objective meaning to our lives is to make sure we continue to have one; that we continue on as a species in this indifferent universe that we find ourselves existing in. Given the complexity and wonder of this plane of existence, it's easy to feel that there MUST be something that intricately, knowingly, and deliberately intertwines us all to some greater purpose in this world.  I am not a religious person, and I consider myself an atheist when it comes to the abrahamic god. Any god with a distinct human-like personality is usually just a by product of the creator him/herself (a person). Societies often have jealous, angry, vengeful, and all too human-like gods.
I don't have any convictions. I don't believe right and wrong exist, only our ability or lack thereof to empathize with others. When we see something happening to someone else, their expressions register in our minds, and depending on whether a certain area of the brain (it's been thought to be the anterior insular cortex) functions properly, we may or may not see ourselves in their position; we may feel ourselves being subjected to the same action that evoked their expression. Laughter is contagious, sad movies make you cry, the torture of another human makes you uncomfortable...this is nothing new to us. This is the principle behind our ideas of what's wrong and right...it ultimately comes down to what you do or don't want happening to you (assuming you're not a masochist or have a damaged a.i.c.). That is why I believe in the Golden rule as a moral guide.
Other than avoiding jail time and adhering to my own conscience, I don't pretend to know or do what's right or wrong. There are reasons why people do things, and all those reasons stem from a brain that they have little control developing (due to genetics, epigenetics, environment, etc).  Your brain is  what controls your life and the life of others. When you know that, when you know how little free will you actually have--you begin to doubt things like morality.
