Author, given how extremely common the topic of the Seven Deadly Sins is in horror writing and plenty of other genres, I recommend getting the base idea polished up in the Ideas and Brainstorming forum before you try fixing the draft. Go to that forum, post a quick summary of the concept you want to write up (don't link the draft unless someone asks), and reviewers there can help you make the idea more interesting and give you some advice on structuring the eventual article for smoothness of reading and narrative. What you have here isn't particularly interesting as-is.
Additionally, your containment procedures are kind of random and seem unnecessarily specific for reasons not apparently related to the object itself. I recommend reading this guide on containment to get a feel for how to write more logical, resource-conserving procedures. Remember, containment isn't based on just having a bunch of cool things, it's about keeping these things locked up. If there's a thing that's just a table, why does that table need to be given food?
The formatting is also pretty sloppily done, with the bolding and capitalization in the interview being inconsistent. Also, the interview is just straight-up convenient exposition dumping, which a lot of audience members get pretty skeptical about these days.
What grade are you currently in at school? Most successful SCP authors have at least some college-level writing experience, since clinical tone is typically covered in college. If you haven’t encountered clinical tone or writing analytical essays in school yet, it can be hard to write an article that possesses the unique "flash fiction as written by a professional scientist" tone the site audience is looking for. If you tell us where you are academically, we can recommend some materials you can study up on, such as these college resources for clinical tone:
