Would you consider non vegan products if it's 100% guaranteed to not involve animal harm/ exploration or animals who died of natural causes?

Basically I'm wondering if you are a "no animals at all"-vegan or "no animal harm/exploit"-vegan, I'm not trying to insult someone, I just like to ask ethical and theoretical questions

\- would you consider non vegan products if the animal is guaranteed to have a better life as they would have in nature?

\- would you consider non vegan products if the animal died in nature and of natural causes? Like leather for example?

(Someone said they just don't like the concept of dead skin and that makes total sense tbh)

\- what are your opinions on vegetarians? I've met people that are totally against everything that isn't vegan and some who are positive about it even if they wouldn't be vegan
