The six human souls and their significance. (Soul 'mode' discussion).

[Slarstorm]

If you ask me the soul 'modes' that are activated when you fight certain monsters don't represent the monsters themselves, but a part of you. In other words, how you defeat them.

For all intents and purposes lets say that befriending an enemy counts as a win for the virtue, while killing the monster counts as a failure.

Blue soul. Jump mode: (Integrity/Kindness).

In the case of Papyrus defeating him without killing him shows Integrity, that's how you beat him. Killing him can be considered a failure of the virtue on your part, you don't have moral principles (Sans in genocide further solidifies the lack of moral compass).

Purple soul. Trap mode: (Diligence/Perseverance).

Muffet, the spider lady traps you on her web, personally I'd say perseverance is the example here. You are constantly being hindered by Muffet, success in the virtue is waiting her out, killing her is sloppy and impatient.

Green soul. Shield mode: (Kindness).

While Undyne is bent on justice, eventually your kindness will win her over. You choose to defend yourself and your morality. Unless you're playing Genocide, since strictly speaking murder is not considered a kind gesture.

Yellow soul. Shooter mode: (Justice/Temperance).

So, Mettaton wants to kill you to put on a show? No thanks. Wearing him down can be considered temperance, as he's not all bad. Killing him is giving into restraint, it's unjust.

The other two, patience and bravery/humility can be considered a constant throughout your adventure.

Aqua soul. (Patience).

throughout the whole game will lead on to the best ending, failure of this virtue would be 'killing out of frustration'.

Orange soul. (Bravery/Humility).

Bravery can also be considered a constant, as well as humility, in order to succeed in a pacifist run you need to put others before yourself, and push through. Failure would be cowardly killing, putting yourself before others.

Feel free to elaborate on this.
