well without wanting to spoiler to much from the novel paul did search for all the missing people and got into the bottle because while he had some success early on but after around half a year till now he only found corpses
what he expected from rudi wasn't to find everyone he wanted rudi to go and find their family while he finds everybody else and cut to the happy end
well but with him finding more and more corpses and remains he got more afraid of finding corpses of his wifes or children so he started drinking to take the edge off
he is still a douche, drunkard and coward but at least the drunk part is understandable
also just fyi because rudi was so brilliant and unlike himself paul has never realy accepted him as his son just like rudi has never realy accepted paul as his father... well lets say till now
which was also another reason why paul placed such expectations on rudi: "he is a genius isn't he so why can't he just solve it or even prevent the tragedy?"
i believe he actualy asked that in the novel and got punched in the face for it
