What if the homunculus argues that it, as a new and distinct being, has committed no crimes, and deserves to live? What if it begs for its life as you load it into the teleporter to split it back up into your science officer and annoying morale officer shoot it into the sun?
Homunculus is a little person that is proportional. You cant merge two tall, fat fucks and get one little person. 4 or 5 homunculi, maybe. But not one.
Like build one really really big space trabuchet, loaded with a space hotel with all the amenities possible for basically a one way generational ship. Then blast those fuckers towards alpha centari and call it a decade.
Oh, and just for fun, give them one life pod but it only holds 20 people.
But the real kicker? ...they never left the ground And it's all televised.
The launch sequence? Really fast merry go round.
The "artificial gravity"? Lol
The infinite food sources vending machines? Catering.
