You are wrong.
I am not legally insane, but I would love to go to mars. As for kids, sure, let me donate to a sperm back I hold all rights to, give me a willing female PHD on mars as a backup, and we are good. I will be the first guy on mars, women will be begging to use my seed here on earth - thats why i would leave a supply behind - and the money can be spent on things I care about here on earth while my kids would eb well taken care of, so its win-win. As for kids on mars, sure, but its something you have to really plan for due to the hostile conditions. I wouldn't be surprised if the first trip is all of the same gender to not create issues.
You are the one with mental problems; why would you have such a low self esteem that you cared about the world you left behind? Better to think of the future and all the great things you could explore OUT THERE.
