Those who left huge stash of Bitcoin in their portifolio and died even when they have seen some negative sign about their health status, to me I will classify them as wicked people I mean that's not the best thing to do. Imagine having like 50 to 100 Bitcoin and then giving up the ghost without selling or letting anyone know about it, is it not a waste of investment. Just like I said, if they have someone they can share there seed phrase to it will be fine.
Why do you think so? Sharing of one's own property with others is personal and is entirely up to the owner of the property. If a person has a large amount of bitcoins in his wallet and does not want to share it with anyone i.e. does not share the seed phrase of his bitcoin deposited wallet with anyone, then it is not right to classify him as a bad person. Having bitcoins in a wallet may not have any detrimental effect on bitcoins if they are not sold and remain in perpetuity.
There are also many investors who have a lot of Bitcoins in their wallets but those investors have not shared the seed phrase of their wallets with anyone, as a result of which those investors are lost but no one can access their deposited Bitcoin wallets.
