to be autistic, the outbreaks only happened because of Ashford, Marcus and Birkin's incompetence, Wesker was the one sane man who dipped out ASAP with all the relevant data and viruses.
Oh and Spencer, he was also competent but surrounded by Machiavellian assholes, he was evil as fuck but he never desired mass casualties, he really thought he could sacrifice a few human lives to uplift humanity and himself to God status.
Ashford was a retard who bankrolled the affair, smart enough to start on some things but his attempt to clone his genius ancestor bore one genius and one retard who royally fucked him, and his holdings and their family lineage up.
Marcus was incompetent in that he didn't see the company coming to clean his ass out at all, he then had a psuedo-second lease on life and decided to start one of the greatest biological disaster events in history out of pure spite and tard rage.
Birkin seeing this, somehow failed to see the same event coming for his ass and literally 4 dudes with sub machine guns waltzed right into the secret base and just shot his ass, he then tipped the biological event into unsalvagable levels with his tard rage and G-Steroid fueled revenge, MIND YOU, by that point so much virus leakage had already occured that Raccoon city was FUCKED, but it really got out of hand quick with him.
