For most types of crimes, I’d agree. This one just doesn’t make sense though, there was no intention or malice behind it. It was an accident because he wasn’t paying enough attention, the particular intersection was shit for sightlines, and he lacked the education and experience to handle it.
Other immigrants are not going to look at the deportation and go “I’m going to pay more attention while driving a semi-truck in rural areas” because of the deportation rather than the 8 years in jail and massive guilt of killing people.
