If your reasoning implies ~X, then X implies that your reasoning is wrong. And if X implies that your reasoning is wrong, then evidence for X is evidence against your reasoning.
In other words, you have no idea what you are talking about. The fact that something has "distasteful implications" (that is, that it implies ~X, and there is evidence for X) does mean it is less likely to be true.
Evidence that killing is wrong is certainly possible, but your statement "I think that killing is wrong" is such weak evidence that it is fair for us to dismiss it. You may provide reasons why we should think killing is wrong, and maybe we will accept your reasons, but so far you have not given us anything worth considering.
I think that you are also equivocating on the word 'imply', suggesting that 'distasteful implications' means something like 'logical implications'.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
