well, first up, not everybody reacts to news like "your fiancee was kidnapped by a vampire" with logic.
mathias seemingly left the castle, but even so it was walter who put the eternal darkness curse on. having death steal walters soul into mathias' stone negated walters curse, so mathias himself would have to initiate his own eternal darkness curse.
walters reaction to elisabthesa's death? again people react differently. thinking that by following gods will everything will be alright, and coming back to find your wife dead (provided you actually loved her), that could cause one to lose their faith, or possible insanity even. going by other works of fiction, you can have brilliant, yet crazy characters. either way it all boils down to different people having different reactions.
cause of her death was pretty much implied to be a terminal illness(or whatever passed for terminal in those days anyway).
leon's only goal, originally, was getting sara back, so it makes sense that he would take her to rinaldo for safe keeping. this, of course, leads to tragedy and furthers his resolve to finish walter off, which he intended to do before he got her back anyway.
