Superman's life on Earth with Lois and Jon is a blessed one. I have no doubt he knows this. But weigh that against all this... all these lives that were allowed to continue... as well as the new generations that would stretch into the future... and the temptation to embrace this is obvious.
I remembered that storyyou and Supes tell. About the orchid thing. Where Supes was trapped in his mind. Trapped thinking the whole planetsurvived. He had this whole life... then Supes realized how things weren't so great in that what-if scenario. And so he chose to come back from the orchid thing! And then he knew this life was better! Even with the... sad and whatever. That's a pretty good gift, you've got to admit. Knowing your life is a worthwhile life. So that's what I got you. For your wedding.
My story is well known. I'm from the future. Where, sad to say, I messed up. Royally. But I'm here to make up for that. To help. 400 years from now, there will be fewer differences. A better time when countries and people will unify. Problems that seem major now will be long-forgotten trivia by then. But the way you screw-ups are handling things is beyond belief. The fools I see running governments jeopardizes that better tomorrow. There will be a Justice League International. Whether you want it or not.
We put on masks, capes, and tights. Convince ourselves we can't be hurt. That we're invincible. But when reality arrives and smacks us upside the head with a wake-up call-- It becomes clear that we're lying to ourselves.
