You need a higher standard than corruption to ruin the career of a Supreme Court justice? Seriously? (I assume you'd say the same of Trump.) What's your standard--a mass shooting by Thomas?
This is the highest court in America. The justices are expected to have ethical standards but the conservatives clearly don't. Scalia was much the same. Justices shouldn't be speaking at political events--but the conservatives do it. I've not read of similar behavior by the progressives on SCOTUS, and if they do they should be called out, too. You don't go on expensive junkets with political activists and corporate executives if you're a judge. This isn't rocket science--but apparently it is for some people. This is a man whose wife is a wacky extremist and who helped organize the Jan. 6 insurrection and Thomas did not recuse himself from a case related to the riot. He's a fraud.
Clarence Thomas has always been a joke. Besides being corrupt, he's the biggest lightweight in the history of the court. He should never have been nominated in the first place. He went 10 years--10 years--without asking a question during oral arguments before the court. He's just a water carrier for conservative issues and always been---has never shown any independent judgment. Most Supremes do in fact show independent judgment on some cases--they do not follow their judicial leanings (progressive, conservative) on every case. That's not the case with Thomas.
