In one word, it is "blessing." Blessing implies increase, it implies positive energy, it implies building and growing. Curse implies destruction, negativity, harm. We mus choose blessing over cursing. We must build ourselves and each other up, instead of tearing each other down.
Thus, anything which makes the world more livable, more lovable, more beautiful, is a blessing, and is a choice of life. Those who worship death, who dispatch suicide bombers, etc.. worship the curse.
It is a paramount Jewish value to fill the world with all manner of blessing, including art, music, morals and kindness. End of discussion.
