Why do innocent people lose in court?
One thing law teaches us is that a good cause does not produce victory or justice. Good arguments produce victory or justice.
Right or wrong, bad or no argument will lose any case.

There are no middle grounds in life as action or inaction leads to consequences.

A person often meets his destiny on the road he took to avoid it - Jean de La Fontaine.

Diverse (and sometimes contradictory) adages and proverbs shed light on this fundamental fact.
"Look before you leap" warns us against bad and/or hasty decision making.
"He who hesitates loses" warns us that inaction or late action lead to unpleasant results.

People have had very different outcomes depending on their response to identical situations. E.g. the case of Bill Gates and Gary Kildall (who's Gary, you ask? That's the point).

The effects of action or inaction always yield compounding results, good or bad (Matthew 13:12). This leads to the rich getting richer and the poor getting poorer.
This is the Matthew effect - advantages beget advantages and disadvantages beget disadvantages.

Life is like an examination. The questions are situations and the options are possible outcomes.
The critical difference is that you can't opt out of answering any question. If you don't choose an option, you will get the "default" option.

Being proactive is like traveling through the waters of life on a boat. To a large extent, your speed and direction are within your control. Also, you are beyond the reach of any animal that might want to take a bite out of you.

Being reactive is like drifting on a log. For the most part, you go where the current sends you. You're wet & not in a very cheerful mood. And you're within the reach of sharks and other like-minded creatures.

In the right situation, you're afforded a large margin of error. Little misdeeds do not turn the tide against you like bad posture on a boat does not impede your progress.
The best posture has very little impact when drifting on a log. A bad posture will worsen your general situation - which is already bad enough.
This is why the loss of a significant sum of money to a rich person might be a rounding error on his balance sheet.
A slight gain rarely does much to improve the financial position of a poor person.

Our boat and log analogy helps answer the opening question. The innocence of the person on the log will not make the log better. The guilt of the person on the boat will not make the boat worse.
The choices and and actions taken by both travelers determine their outcomes.

Choose a boat.
