[DC] Why not just Boomtube Doomsday to the furthest possible Galaxy? space expands FTL and even if Doomsday is FTL he'll take forever to get back.

He always seems to find his way back

And on top of that, he's too powerful and scary for bad guys to just leave him. 

Case in point, they sent him to the end of time and Time Trapper grabbed him before he was completely obliterated and brought him back.
