I did not say salamanders, I said "The Salamanders", which are a group of Space Marine loyalists, and perhaps the only loyalist chapter capable of understanding mercy and compassion, as well as occasionally going out of their way to assist innocents in need. Completely different. tl:dr: I think you misunderstood. Or you're just making a joke, in which case never mind.
Seeing as Pro neglected to define the term 'The Salamanders' in Round one, I shall continue to refer to them as 'newt-like amphibians that typically have bright markings, once thought able to endure fire.'
My second argument is that since the definition of the word saint is 'A person acknowledged as holy or virtuous and regarded in Christian faith as being in heaven after death', salamanders cannot by definition become living saints as the living can't become saints. In addition to this salamanders are not people. Finally, as they are inherently evil they can't become saints as this renders them incapable of being holy or virtuous.
To presume something to be evil just by looks is wrong and bad. Therefore you would not be virtuous enough to become a living saint, and could therefore be lying. Or I'm just bored at this point. Take your pick, vote Vulkan He'Stan 2016. (Or 42,000. Whichever.)
