In all honesty, I think I would be likely to commit all of them, if I haven't already. Which I know that I have so I'll go into brief detail on each. Information taken from Wikipedia.
Sloth- it was first called the sin of sadness or despair. It had been in the early years of Christianity characterized by what modern writers would now describe as melancholy: apathy, depression, and joylessness - the last being viewed as being a refusal to enjoy the goodness of God and the world God created.
I can't say that I've witnessed true despair though in some moments in life I've felt like it could be said to be true. Although I have gone through different stages of depression, and have also looked with shadow tinted glasses at the world.
The modern view of the vice, as highlighted by its contrary virtue of zeal or diligence, is that it represents the failure to utilize one's talents and gifts. For example, a student who does not work beyond what is required (and thus fails to achieve his or her full potential) could be labeled slothful.
In this definition as well I can honestly say that I have sinned. Perhaps I am a bit slothful.
Greed - No need to define this.
I have often felt greed, though I may not act on it. I've wanted things that aren't mine and that I'll most likely not get.
Lust- can't deny that I've experienced lust in plenty of forms be it sexually, or the lust for material things and emotional acceptance.
Gluttony- is the over-indulgence and
over-consumption of anything to the point of waste. In the Christian religions, it is considered a sin because of the excessive desire for food, or its withholding from the needy.
I can't say that I have witheld from the needy, I often give away what I have to those I love/care about. However, I have been known to binge on icecream >.>
Anger- I am sure everyone has felt true anger at one point in their life. Being toward a situation or person in their own life or for a situation and person they have never met, only heard about or imagined. I often feel anger for things that do not concern me so perhaps I am particularly wrathful?
Envy- This goes along with greed. I want things I can't have and a lot of times envy those that do have those things.
Pride- ahh...Pride. I have that in spades, even while I know that I should tamp it down.
I believe its safe to say that I have commited all of the seven deadly sins in various forms. Hmmm...Should I be worried?
