All Israel

What do you think about the issue of all Israel being guarantors for each other, like a couple on a ship and a man makes a hole and they ask me what a seaweed does? So he says he only does it in his own place, and you answer him, "You're right, you do it in yours, but we'll all drown!" Is there a connection between the offenses and sins of Jews towards each other? In other words, can observant Jews be punished because their fellow Jews are secular and do not observe the commandments? Can the redemption (what is it?) be delayed because many do not observe the commandments, while if Israel had observed two Sabbaths, they would have been redeemed immediately?
