Your question was deleted by the Roomba, an automatic process that removes questions that meet certain conditions (this link appears on the word "deleted" at the top of your question). In this case, your question met the
RemoveAbandonedClosed condition described on that page, as it was closed, unanswered, did not have a positive score or reopen votes, and had not been recently edited.
Perhaps you're wondering why it was closed in the first place. Your biggest problem is it lacks focus—you've asked multiple questions, some of which (comparing all the differences between areas of law) are quite broad themselves. You've also asked for this comparison between three countries. You could probably write a book on the topic—it's too much for a single question/answer on Stack Exchange.
You've also asked a few opinion-based questions, like why the law sets the penalties the way they do. These sorts of "why did politicians enact the laws that they did?" questions are off-topic here, but may be on-topic at Politics Stack Exchange. You'll want to read that link before asking there, though.
In summary, you should stick to a single, fact-based question about what the law is (or was in the past).
Finally, you ask if you should modify the question. If you want it to be answered, you'll definitely need to address the reasons it was closed, but since it's already been deleted, you should just ask a new question with the problems fixed. Trying to get a question undeleted is far more hassle than it's worth when there's no answers worth preserving. Just make sure that you've actually addressed the problems and aren't simply re-asking more or less the same question.
