As a huge fan of the comic (the show is slow, unbearably so in season 2, I assemble papercraft dungeons while watching), I can tell you that the others are right in thats it's drama.
Now, your characters actions are perfectly fine given the end of civilization, however, in the light of the comic, characters that shed thier humanity too much end up as the antogonists to the central cast.
Now, if you play your character as having regret and/or emotional shock from having done what he thought was required to survive when things calm down, that could bring him back into line with the party as everyone tries to wrap their heads around the horror around them.
At the same time, every time things try to go the democratic route for every decision, things end up going badly, where those willing do break the societal norms of Pre-Z end up trampling on those trying to be civil, paralisys due to group indecision, internal sabotage from marginalized votes, hoarding and hiding of weapons prevent internal violence right before an unexpected Z attack. Petty jealousies get magnified by the events of post-Z life.
I strongly suggest reading the Walking Dead comics. It's a great read. The show needs to die a flaming death.
