It's a haphazard morality play which accepts that individual wills are to be bent to suit not just the rights of contemporaries, but the rights of potential people. This logic is applicable without time travel being involved, obviously--and I don't think its necessary corollaries were intended.This is why "Children of Time" is a worse episode than "Let He Who is Without Sin."
Somewhat off-topic, but what is your criticism of Children of Time, precisely?
From memory this episode deals with some of the questions you outlined in your earlier post, i.e. who's to say which version of the universe is better?
Oh, back to bizarreness in Destiny--the Columbia spends a lot of time at high impulse, close to c, and subject to dangerously blueshifted radiation. Now, one or the other of these things is true--impulse is a newtonian, reaction-based and relativistically-limited drive, and thus Columbia does not have near the reaction mass to accelerate itself to anything like near-c speeds; or, it is a non-relativistic drive, and blueshift and time dilation should not apply. Others understand the science better, so can correct me if I am wrong, but I'm pretty sure you can't pick and choose.
