i do think vince mistreated e. the entire season 4 vince kept doing what e didnt want him to do and thats why he failed. e wanted vince to do A2 for 12 mill (which is what he got for him) but vince was too set on doing medellin, which e knew was garbage right away, but vince loved billy walsh too much to realize it. i think if you look closer, you'll realize most of vince's failures were because of his actions and not because of what e and ari were telling him to do.
