As humans we are vessels of passion beyond compare. Unlike any other being on this planet, we are capable of so very much with that power. There are options that can inspire the lowliest and bring hope to those that have none, embolden the weak or bring justice where previously reigned chaos. Yet equally, we also have such ability to cause strife, hatred and pain.
Its a fact of life that humanity is split between the two though as free-will makes it this way. I see this as a good thing, though, as it ensures that each act of generosity and kindness is all that much more powerful with knowledge that the person behind it is doing so with conscious thought - and that most individuals thereby have a genuine potential to change their ways. Being railroaded into a particular morality (much less everyone being that way for a particular one) would be pretty boring anyway, right?
In short, we're all big pots of paint really. Its what you decide to do with that paint! Whether you're indigo or lavendar is a different topic altogether. Lulz.
