I did not fail to realise anything... an age old scientific question still persist... prove to me you are self-aware and sentient. Till today we have no way of doing so :) I am sure you can prove it to yourself (following your own qualifiers) but you cannot prove it to third party. Furthermore, sentience does not have to lead to scientific discovery or event to any kind of enlightenment, assuming it does would suggest that universe only follows along certain lines (which would disregard existence of chaos all together) and I could argue that our actions are often motivated by instinct and will to survive (and healthy dose of self-interest) than actual thought out decisions (I am playing Devil’s advocate here). I do agree with one being responsible for one's actions, but only to themselves and by being a part of group, to that group by right of participation and resource sharing. Finally, let us define good and evil by using colourless room example. An individual raised in a colourless (black and white) room has no concept of colour (blue or red) apart from definition of it as it has been taught to him by third party (if such party existed). When confronted with such colour they would have no idea what it was. By extension an individual raised in an environment with absence of light (darkness) has no concept of light or darkness since only one state exists to them. The definition of good and evil is used to describe actions or results of actions on individual or group. One cannot exist without the other and if an individual exists only in one such state they certainly have no concept of another. For us they may appear “evil” by our definition of the word, for them, they just “are”. The rest is nothing more than a justification of your position. In the end and in relation to the original post, I choose to fight the other side (some call it Darkness) because I want to ensure my own survival and the survival of ideas I champion (some call it Light). I do not use terms such as good and evil to justify such choices to myself or others. And for the record, my main is Titan but I do maintain well trained Hunter and Warlock :)
