What do we mean by making a judge?
In order to make a judge you will have to weed out certain elements, from the prospective judge, weed them out completely.
Then you will have to trim certain elements , prune them as per requirement and teach them to keep on pruning at such intervals as and when required.
Then you will have to locate those elements whic  though present are not in optimum form or quantity of not of standard quality.
You will have to treat them , manure them, take extra care of them and teach the prospective judge that these are the characteristics that have to be maintained at least at this or that level.
 Ultimately you will have to raise endurance level, boiling level, survival level of the person to withstand the extreme requirements of the job.
Then you will have to tell them, teach them what they have todeliver. let they be made familiar in allitsdimensions about end product they have to deliver.
Divine thory of law and judge is no longer in practice. It cannot be advocated in any form.

And ultimately conceive possible risk factors, apprise them of those, show them those, let them feel the extreme actions,reactions and expose them not through words but through live demo.
Let them know the tools available to manage the risk.
Demonstrate live.
Let them know the art and technique of using those tools. Again demonstrate the whole process.
This demonstration should be chartered in a way that it is suitable only for a judge.
