Generalizing people  will never be right no matter what angle we look it from. It’s true that there are bad people, so as with bad teachers. They might be motivated with something wrong, but that doesn’t mean that all teachers possess the same character! We are all different. There are people who choose to be bad, and there are also people who choose to be good one  and I can feel that it would be so unfair for the teachers to see them as bad people just because someone messed up. As a lab report writer , I understand people's differences.
