This isn't a Christian thing, or anything religious. Your religion or ethnicity, doesn't matter to me, if you have one then that's fine, but this question is moreso for fun, and to learn a little about one's self.
I'm not going to participate in the poll, but I will share what my sins are. I can tell you right now, my primary sin is Lust. I don't do anything to others, as I lean on the submissive side, but I can't deny my lust is real. I wouldn't jump into bed, the first chance I get though, as I'm not one to simply give it away.
I guess, I'm somewhat of a glutton. I got a mildly protruding belly, my family calls it a beer belly, I don't like it and I wanna get rid of it.
I feel this is more because of my depression, but I would say I have the sin of sloth.
And envy. I crave love, I want someone to share it with, and I feel envious of those who have it.
I'm not a yandere, I'm actually the polar opposite of one, as I would rather my potential partner leave me, to find their happiness elsewhere, rather than make them stay in a relationship, I feel they are unhappy in.
Now, I can't say this fits for all yandere, but I have analyzed some details, and discovered some potential sins, one might expect from a yandere. An average yandere's sins are likely pride, envy, greed, wrath, and lust.
Pride, is a sin I figured would likely be a prominent sin, as they would likely feel, an overhaul of deserving the love and affection, from their target partner. They feel no reason their partner should reject their love.
Envy, seemed to fit, well, with the jealousy, they usually feel when they see their target partner with someone else.
Greed, is quite common in the trope, as they often don't care to share their partner with very many others, if anyone at all.
Wrath, is something that's kinda hard to imagine a yandere without. It's a part of a yandere, that is unleashed, when they feel a sense of disloyalty, betrayal, or an invasion of their "property".
Lust, though it is normally sexual, it can also refer to the overwhelming infatuation they have towards their potential partner. Other times, it can be—or become—a sexual fixation, as well.
Don't hold me to this, however, as it is just speculation. After all, as I said, this is just for fun, and no judgement will be passed. I'm not a God or anything. I'm just curious.
What is your sin? Feel free to mark all that you feel apply, and leave a response below, if you want to explain yourself. Just be aware, if you put something incriminating, that's out of my hands.
If you want to message me personally, then feel free to send me a private message, at anytime. Ask me anything, send me anything, call me whatever you want, in a private message, I'm up for it. I also, posted a response to the "Dating profile/stalking permission" thread, recently. If you want to check that out.
I really hope that some people participate in this, as I'm curious what what sin will be the most prominent, in the end. Anyway, I'll leave this to everyone to have their fun, and please let me know if I got the yandere sins right, for any individual, or maybe I missed some. As I said, not every yandere is necessarily the same. Few, may even portray pride, but this is all for fun.
Note: Apparently, you can't have the same number of answers and votes per person, so I'm adding an extra, option. I'm sure a few people will choose the extra answer, though, but hopefully most will answer as best and accurately as they can, to keep it enjoyable. Either way, I'm sure it'll be fun.
