♔ — Does your muse believe people are innately good or innately bad? Why do they believe this?
He doesn't think people are either inherently. He thinks they're made one or the other by their circumstances and the actions they take because of or in spite of them. Sure, you can say someone was just 'born' one or the other, but he thinks that's just an easy way to slip into making assumptions about people. A person isn't inherently any more good or bad than any other animal- it's their choices that make them fall into one category or another.
♘ — Do they believe humanity/their species, as a whole, to be moving in the ‘right’ direction or the ‘wrong’ one? Why do they believe this?
Honestly? He's probably never given a thought to humanity as a whole. Thaddeus tends to keep to the bubble of the existence he's trying to protect, and doesn't give much thought to external things unless they're actively bothering his home. Besides, what other people do really isn't his business- everyone makes their own choices, and they have to deal with the consequences of them, that's as far as he thinks, really.
♙ — How hypocritical is your muse? If they can be hypocritical, do they realise this about themselves? How do they reconcile with it?
Oh, he definitely can be very hypocritical, but he also doesn't... really care. Thaddeus is a very selfish person in many ways, and one of them is that he doesn't always apply things to himself the way that he would to others. He realizes this, but he just... can't be bothered to think that what he does can be considered the same as when someone else does the same thing.
♝ — Is your muse concerned about being remembered after they die? If so, do they have anything specific notions about what they want to be remembered for?
Nah. He's neither heroic (in his opinion) or attention-seeking enough for that. Oh sure, he's a showoff, and he'll always gladly put himself out there when he feels like it might be fun but... Apart from protecting his home, Thaddeus is someone who tends to prefer to exist in the 'now' rather than think too hard about the future.
(It's unfortunately likely that it's because he doesn't think he'll have to be worried about living that long, but hey-)
