If some group of the population is responsible for 85 to 90% of the spread of a disease, then they are directly harming also all the other people who can't be vaccinated for health reasons, they are helping the virus spread and mutate more often to promote new variants that the vaccinated people might not be resistant to, and they thus are the main reason why we still need to have measures in most countries to limit the spread. If you're not seriously doing your part, then you are actively supporting the virus and working against all the rest of the population that is either unable to get critical care or just tirelessly working in the healthcare sector treating all those avoidable critical patients.
