Based on a cursory view of the available history of failed Soyuz missions, and particularly those involving the abort mode, what you said is empirically false. The cosmonauts on the failed missions were not punished, and in those missions where they survived, many of them went on to crew later missions.
You are being downvoted because you tried to introduce a "does anyone else think Soviets were nasty evil people?" rhetoric into what was previously a technical discussion.
Also, the gp commenter seems to misunderstand what 18g would do to somebody. For an extended span of time, that's a death sentence. For just a moment, it's likely going to knock you out, but it's survivable by healthy people and it's far better than being in a rocket explosion.
You're being downvoted because you have an incredibly poor understanding of the Soviet space program.
Yuri Gagarin's first flight was in 1961, 8 years after Stalin's death. The purges have long stopped. The constant hunt for wreckers did, too. Yes, there was still political repression, but it was for political action, not "Oh, the project went up in smoke, we're sending the entire team to Siberia."
There was both a disregard, and a regard for safety in the cosmonaut program. Disregard because of heavy political pressure on deadlines, regard because it looked really bad for a cosmonaut to die. The track record that resulted was... Mixed. Could have been much better, but not a complete horror show.
After the failure of Soyuz-11, for instance, the program was grounded for 2 years, the Soyuz capsule was redesigned, and the number of crew in it was reduced, for safety reasons.
