No, kelnos, there exist unvaccinated that take all possible precautions not to be spreaders. I know people (asymptomatic supposedly non infectious but-you-never-know) who lock the car windows and airflow when they pass into inhabited areas; I know people that have broken shoes and are not going to a shop to replace them (I am not joking). Their cynicism is at level "if a particle roams the air and enters the window, tough luck..." - if you want to blame at that level, ok. (If you want to also note the damages for the shoe industry and all the equivalent, that would be understandable.)
Other people are much more leaning towards frowning upon the partytime people "let us hug and stay together and forget about it all". Those other people believe that if people had been careful, the damages would have been minimal. Using some of your words,
«the virus could be [...] controlled by now in any country with a sufficient» carefulness in the population.
