You can't spread the virus if you don't come in to contact with others -- minus animal transmission.
Given the vaccinated can still get infected and spread the disease, it begs the question if they're not being totally selfish by not self quarantining at the expense of everyone else?

Nothing about preventing disease is "all or nothing", it's all about risk reduction, which is why vaccines are important.
Total quarantine for everyone is obviously unworkable, so suggesting that vaccinated people do "Self quarantining" is not a workable alternative to practical risk reduction measures such as vaccination and masks.
I'm saying that equating those that choose against the vaccine to being "selfish and lacking compassion" is wrong and dangerous.
