In my personal opinion, if I'm watching a sporting event, and a team is proven to have cheated, they should be disqualified from the contest. If they scored the most points, points that are assumed to have been legit and unrelated to the cheating, they should still be disqualified. This would be FAIR. Break the rules, suffer defeat.
"It's not whether you win or lose, but how you play the game."
The same should apply to our elections. No one should be allowed to benefit if they are cheating, even if the cheating didn't result in the number of votes the cheater won by.
We have plenty of evidence of cheating -- poll and counting area observers being obstructed/kicked out, signatures being ignored or mismatched signatures not disqualifying ballots, Democrat voters being allowed to fix ballot "errors" but Republican voters not being given equal treatment, machines which had problems the last 4 years being used in 2020, etc.
Excuses of this being human error and that being a "glitch" don't cut it. If the opportunity to prevent these things existed and no one did it, that's allowing problems to continue which seemed to all favor Democrats.
There are way more instances of fraud than have been proven, and some are on both sides, but most of those were individual, not party, instances. But, when 170,000 ballots for Biden were from counties reporting zero registered voters, we have to assume these "irregularities" were intentional.
At a minimum, certification should be blocked. Optimally, the cheaters should be ejected from the "game".
