@BenCodie, I think that forming a strong opinion on every issue isn't always possible; it kind of depends on how we personally see things. "Lying" is a pretty big word, and the context surrounding it can totally change how we look at it. Yes, if someone has been proven to be a liar, it's fair to be a bit wary when dealing with them. Trust is usually built on what someone has done before, so if they keep lying, it can make people see them as untrustworthy. But it's kind of a tricky thing that can change depending on the situation. Not all lies are the same, if you get my drift.
