He was working for the DNC in the IT department of somekind if I remember correctly. Something in regards to voter registrations as well.

But what about having a wife and kids or a legacy to be proud of?

He realised the DNC were corrupt and faked the results of the presidential nominee, which would have gone to Bernie.
He leaked the damaging DNC emails to reveal the corruption.
So Hillary had him Killed.

Do you think Hillary would have won had he not done those things?

Man, what a chad, lucky bastard. Getting killed by the cabal is a free ticket to heaven.

No, Trump was always going to win against Hillary.
Would have beaten Bernie too, but for different reasons.
Wikileaks have a reward out for leads on Seth’s murder. That tells you all you need to know.
