I actually agree with you for this one.

But let's continue.
As the professor asked again in the next case, is it Ok to push a fat guy onto the track to avoid killing 5 people? If it is not Ok, then why is Ok to turn the car in the first case?
What is your opinion in the last real case? Is it Ok to kill the cabin boy?

Can we say that philosophy makes things complex sometimes, a murder is a murder????
