Life is too short to question, but so is the future and past. Honestly, the present is what matters most of all. Be true in your present, and the past/future will become more easily understandable.

Life starts with a capital letter, and then dies with a period. How long and fancy we decide to prolong it is up to us.

Do not become unbecoming towards mankind, for mankind isn't unbecoming towards the selfish.

... yes, religious authority is important, but you forget one thing. Without willpower, we would be slaves and with it, we would be rebels. Obedience, my friend, is the key to understanding willpower, and willpower therein lies the understanding of common man. Truly, to say that religion is unneeded... Commoners need heteronomous obedience. That much is sincere. Ideology? Don't make me laugh.

If you never love you never hurt
If you never hurt you've never lived.
Love in life and embrace all the pains that come with it. 

The pain of having lost something is never equal to the pain of having lost someone.
