Good movie but it doesn't make sense

Rating: 9/10 (4 November 2018)

This martyr wanted to kill 7 humans who epitomize the 7 deadly sins, sings of the degradation of society - great so far.
Lets tally up the victims, shall we:

obese man: gluttony
lawyer: greed
drug dealer: sloth
prostitute: lust
model: pride
John Doe: envy
........: wrath
wife and unborn child: no sin

You see the last two there; one victim is not related to a sin (the wife) and there is a missing victim for one of the sins (wrath).
