So you are comparing the innocent people in a multiplayer game to the family of a criminal going to jail?
What is the greater good you are achieving when you are kicking out someone that justifies ruining the games for the other players involved? There is no equivalence between the two situations. We have no choice but to put criminals who are a danger to society behind bars. You have a choice to save the game and "rehabilitate" the offending player by working together to finish the game in time.
Timers are an abstract concept. If the game ends up finishing normally, the violation will only have been theoretical. No one cares if on the game's results page it shows that someone went out of time. People care if the game doesn't have a final score and a fully completed state because someone was kicked out before it could end.
