Interesting. Let me criticize (as in evaluate, not diss the shit out of) some of your points.

I wouldn't call them deadly sins, because all seven of them are naturally inside each one of us, with different proportions and different potential to grow worse in every person. For example, some people are more hot-headed than the others, some people are lazier than the others,etc. What makes them deadly is when we can't control them, resulting to wrongdoings, crimes, degradation, murders, and so on. Those are what I call sins.
Now, if any of you have done any Biblical study and understand what sin really is, it is because they naturally reside within us that makes them sin. St. Paul taught that all of Earth as we know it is under the dominion of Satan, who rules with the power of death. Death
IS sin, and manifests itself in our flesh. It is
precisely because our bodies will one day fail us and we will die that causes us to sin. In other words, what you call the seven deadly sins are merely manifestations of death and our desire to avoid it.
St. Paul taught that, although we will all die, there is a way to save oneself (salvation). Jesus came down to earth and put on a flesh body so he could take all of humanity's sins onto himself. Baptism is a holy ritual that basically makes your body one with Jesus. Because Jesus is God, he cannot truly die, and thus if one is baptised and lives a sinless life, his flesh body will die, but his spirit will live on with Jesus and God in heaven, liberated from sin/death.
With that said, yes, the capacity to sin is within us. Each and every one of us is an amalgamation of our body (flesh/sin/death) and our spirit (mind/salvation/life), which is constantly battling against each other.

In fact, a proper dose of those 'sins' can make positive results. For example, your pride won't allow you to lose to another people, so you strive to be the best. And TV remote control? It's because people were too lazy to get up from the couch to change the channel so the invented it. And it's the greatest invention I've ever know. Just remember that too much of those 'sins' resulting into real sins. Everything is good, but too much of everything is bad.
We also need to remember that, at the time when Christianity dominated all thought (the Middle Ages, which is also when Spice and Wolf was set! XD), the only thing people cared about was to escape sin and go to heaven. Everything was about God and joining him in heaven. To even think of delving into nature's secrets and thus God's work was unforgivable. Reason
was exercised, but was restricted to Theology under Thomistic Synthesis. Therefore, for example, exercising reason to invent the remote control would fall under Sloth (for being lazy) and Pride (for thinking you are worthy of delving into God's secrets to invent the remote control), and would definitely be condemned.
But of course it's impossible to avoid all sin since, according to Christianity, sin is a part of us. St. Paul did say that if you couldn't restrain your incontinency you could appease it a bit. For example, without food, you'll die, obviously, and delaying the satisfaction of lust will result in its buildup with potentially dire consequences; thus, St. Paul allowed marriage, even though marriage (when reduced to its basic values) is all about sex (and therefore lust). Interesting that you bring up Aristotle's Theory of the Mean, where virtue of everything is to know where the middle is. Too much gluttony is bad, but too little will result in starvation. Too much anime/manga/hentai turns you into an otaku, but too little, well, you're missing out big time, pal.

The key to avoid doing sinful things is to know them. That's why religions are born, laws are made by authorities, norms and social rules are made. You already know that rape is sinful and leads you to jail, so don't rape. At least fap :P.
Now, you yourself pointed something out. Laws and maybe even religion are manmade. It's not like they were written in nature. We invented them. For example, who said rape is wrong? For example, one could dismiss all moral values and argue it's conducive to procreation of our species.
In fact, let's take it a step further. Who said reason is inherent in human beings? Reason was simply invented by the Ancient Greeks and eventually adapted by the whole world. And, who said civilization was inherent in human beings either? Again, it was simply created by human beings. If the Ancient Greeks or ancient Sumeria did not exist, who knows what we would be like now? We could even say that we humans are only superior to animals because we invented reason and they didn't, but that's going off topic.
By the way, just to establish something.
I am not Christian, I just happen to know too much for my own good. I'm more of a reason-orientated person, and thus I'm going straight to hell, if it exists. But I'm glad you guys like it.
