My world isn't dark or negative, but we aren't divine creatures. That's all. If you consider that dark and negative, then it's not my problem, and thus don't be sorry, keep it to yourself. Governments, laws, and social systems are designed to suppress the demons of our nature. We learn to be better, we aren't born well-behaved. I don't have a problem with people behaving good, but this doesn't mean they are "naturally good", as if negative thoughts and scenarios don't cross their mind at all. The Saints are the first people to say that they are the worst, because they know their own thoughts and nature even if they are alone in the desert. Describing oneself as "naturally good" is kind of an arrogant statement. At best we are neither good nor bad, but circumstances make us so. You still can behave good in a bad situation (or any situation that triggers an instinctive thoughts, like two different teams triggers the mind to classify people to in group and out group), but you need to exert some effort because it's not natural but the outcome is more favorable. We use our long term thinking when expressing our thoughts. That's why the pre-frontal cortex was evolved in the first place.
