Due to the fact that like other human beings i suffer from confirmation bias, i'm gonna say no. The fact that i am sinning right now by writing and posting this article is a negative reflection on me and not on Christ or the Holy Ghost, or any of those guys/that guy in fact. At the same time, it is cause for concern. Any value Christianity might have is entirely dependent on the extent to which Christians behave better than they used to before conversion, or perhaps better than how they would be acting now were they not Christian.
This is where it gets complicated. Firstly, how someone would have behaved if they weren't Christian is a counterfactual conditional, and it's possible to project all sort of negative stuff onto that hypothetical scenario just to support your belief in your own position. Secondly, when people referred to as Christians behave badly, three issues arise: maybe they're only Christian in name, maybe they would've been even worse otherwise and maybe they're resisting God's will to change them. The central problem here, however, is that i'm trying to apply the principle to others when i should be applying it to myself. I am, even more than usual, in no position to judge here because right now, i have a huge plank in my eye and it would be nice to be able to point the finger at others' behaviour.
As a result, what i have to do now is turn it round onto myself. I know i'm Christian and of course don't know who else is, so i'm aware that i'm not just Christian in name, so that leaves how i would've behaved were i not Christian, something to which my conscious mind probably has no access because of cognitive bias, and one more issue: resisting God's will to change me. This may imply belief in the existence of free will, which is philosophically interesting.
A couple of other things: i have run out of milk and won't be buying any until tomorrow because of my Sabbatarianism, but as a result i will be consuming Liz's milk supply instead. Also, whereas i won't be buying milk, i fully intend to buy ingredients to feed my son this evening. Clearly i am obliged to him in this way, but i still could've anticipated that that would become necessary before the Sabbath actually started. Then again, that would involve increasing my consumption on another day of the week. Hmm.
On a different note, here's an interesting pair of graphs:
