When Perez first entered the house, his gameplan was obviously to pick on the already most unpopular housemates i.e. Katie Hopkins and Ken Morley.
He made several attempts to jump in to situations and vilify the easy targets, trying to encourage a group mentality in condemning and humiliating these people (katie about her husband, Ken the 'homophobe'). When it didn't work, he would cry or wait for another opportunity, but he would thrive on being 'in the right' and the person to tell the big bad character how despicable they were, even if it's not his own fight.
In America there are many reality shows where this 'hero' rallying the troops against the forces of evil mentality is common place and usually works, but in Britain it's rarely ever seen. Perez and Katie are just as bad as each other and will destroy each other in there, but let's not think he wouldn't do the same to her if he could.
