For the same reason I didn't just watch my kids grow up like wood in the forest. That's the superficial reason. A more in depth reason, as I also said in my reply to Marcus, is that I will be always the same I. Hence, it makes perfect sense to me to correct the lies, untruths, and misinterpretations that inform human behavior in order to stop their propagation. You may also call it self-love. But to be honest, those are just rationalizations of the fact that I simply feel like it. Whether I will meet with success or not is inconsequential to me, because, as you said and I agree, the actual outcome is beyond my control. In other words, it’s exactly the same reason why I won’t commit suicide despite the inevitability of my death.
