A clear sense of morality can be an attractive quality, which often draws other people as followers. The traditionalists you are seeking to undermine are likely to look dull in comparison with your sense of purpose. Many of them will have no better reason to prop up the status quo than that they are lazy and comfortable. Understand the risks. You will need to build a small army of supporters to plot with.
Few rebels can overturn authority on their own.
So you must be personable and persuasive. And if you don't have allies, you will have to rely on your own advice - a dangerous situation to be in since your judgment is likely to be unsound in some areas. Any slip could be disastrous if you are suspected of subversion. Astute leaders will get rid of troublemakers like you on any pretext - taking a pencil home, perhaps. Don't expect much success or satisfaction if you are a rebel without a cause.
