In Monster, which feelings most likely lead to Mr. Sawicki’s challenging Petrocelli's view of Steve's character?

Mr. Sawicki is Steve’s film teacher. He runs the club that Steve loves to participate in, and he is one of the few characters we meet that sees any potential in Steve Harmon. Everyone else in the story either sees Steve as a lost cause, a bad seed, or a monster. Mr. Sawicki, therefore, would feel defensive of Steve based on how well he knows him. The fact that Mr. Sawicki has seen his fair share of Steve’s art that depicts his neighborhood and documents the world he lives in helps make him a reliable witness for Steve’s defense.
Petrocelli is seeking to make Steve look like a monster, hence the name of the novel. She refers to Steve as a monster in the opening and closing statements. Mr. Sawicki is fond of Steve, and it is probably affection that leads him to challenge the idea that Steve is a monster. Mr. Sawicki does not lie, like some of the witness seem to, to alter the jury’s view of Steve. Instead, he comes out and presents precisely how he sees Steve based on the time they’ve spent together going over film, planning projects, and learning. His opinion of Steve is high, and he trusts who Steve has shown himself to be. Petrocelli tries to poke holes in that idea by saying that Mr. Sawicki doesn’t see Steve when he goes home, but the point is made to the jury at least that Steve is someone who is not only connected at school but who has potential in artistic endeavors.
