Logical Conclusions

If you extend and idea to its logical end and find something you don’t like is that idea then flawed?

For example an extreme deep-ecology standpoint would argue for the preservation of HIV/AIDS as the virus is living and therefore holds and inherent value. Obviously this is a crock of shit and to promote the existence of something that causes so much misery is morally reprehensible however it has been done.

While I’m sure that most deep ecologists would reject this extreme view does that make the idea flawed? It is certainly what is in the back of my mind when thinking about the issue.

Does this extend to all ideas? I think it does but I’m just not sure.
