It's not really vague, it's a very clear question. And my response is phrased as a question because it depends on your personal morality. No one can answer for you. Plus, I was very curious to hear other people's position on the importance of truth (or lack thereof), and I find that I am compelled to engage in whatever way I feel at the time of commenting.

I personally am not sure how important I think the truth is as a moral good. I feel that as time has gone on, I've seen the dissolution on a societal level, and I now value truth more than I once did.
