The 7 Funkin Sins

ok

Reasons-
Sloth- GF- This is because GF never really does anything to help BF. She just sits on her boombox. Doing nothing else

Wrath- Daddy Dearest- Due to the widely accepted theory that Daddy Dearest trapped BF in the video game in week 6, this means that DD is a very sore loser and gets enraged very easily.

Gluttony- Monster- I think this one is really easy. Monster's entire shtick is eating GF.

Envy- Pico- Pico as envy may surprise you, but it's because of the fact that BF and Pico are exes. And seeing your crush smitten over someone else would DEFINITELY make you jealous.

Lust- Senpai- This is another obvious one. Because Senpai was made for a dating sim, that obviously makes him a candidate for Lust. And trust me, after seeing his "remark" before Roses, you'd believe me too.

Greed- Now this is interesting. We have two options for Greed. 1- BF- This is because BF only wants GF, and nothing else. 2- Mommy Mearest- MM in Week 4 is shown to be clearly loaded, as you are on a limo being driven by a Henchman.

Pride- Skid and Pump- THE MOST controversial out of the 7. Why are they Pride? Simple. They only care about the "spooky month" And because of that, they believe that them celebrating the "spooky month" is more important than anything or anyone else

Ok, hear me out.
I would say Pride could be Tankman. It's kinda already been established that Tankman can be pretty cocky at times, and usually (the only useful thing I learnt in history class), one of the main causes of war is Military/National Pride, where a certain nation starts a war with another for reasons, usually to boost their own morale like "Oh we are so powerful and can crush other's armies!"
Thank you for listening
And also because Skid and Pump seem to care about each other a LOT this doesn't seem too sinful, but they also have an element of greed as they were bribed with candy (CANDY. not really something worth KIDNAPPING, Demonapping?, a woman for) to try and capture GF

Ok. Tankman's Pride now.
Do any of them make sense to you?

Yep that makes sense
The rest also make sense too
