As others have pointed out, everyone has their own logic.
This is sophistry; everyone can have their own, but logic is the same for everyone, much like mathematics.
Some people, when asked "Can I have a cigarette?", immediately punch you in the face.
This is more likely paranoia or something similar; it has nothing to do with logic.

Pure logic leads to only one thing: first, you create a theory, assertion, or conclusion (e.g., Mr. X is guilty), and then, perhaps quite skillfully, you fit the data to it.
AND FINALLY, ABOUT THE GREAT GUY. YES!!! THAT'S HOW IT SHOULD BE!! THIS IS A REAL AND SUBSTANTIAL ARGUMENT FOR THE DEFENSE (but not for the prosecution). AND IN LEGAL PROCEEDINGS, IT IS CALLED A PERSONAL/PROFESSIONAL CHARACTERIZATION. AND IT IS PERFECTLY NORMAL TO BUILD ARGUMENTS IN FAVOR OF THE DEFENDANT, BASED ON THE CONTENT OF THIS CHARACTERIZATION, AND THE VERDICT, OFTEN, DEPENDING ON THIS CHARACTERIZATION, WILL BE SURPRISINGLY DIFFERENT!!
The presumption of innocence, not a personal characterization, obligates one to resolve ambiguous situations in favor of the accused. A personal characterization is taken into account when determining the sentence and is not taken into account when deciding on guilt or innocence.
