They don't completely adopt the personalities of their characters though, it's just that Ainz has a passive ability that calms him down under any situation, which is why he could do and make decisions that he would otherwise wouldn't be capable of doing such as killing somebody etc.. also Ainz acts as the overlord of his own will, because he is afraid that the NPCs would abandon and betray him but aside from that his personality is the same as he was before he just doesn't show it to the NPCs, so to be more accurate it's more like adopting the racial traits of their races rather than adopting the personalities of their characters, Ulbert might adopt some traits of his race (most likely devil/demon) but that doesn't mean that he would completely change altogether and even when he does become more sinister and cold; he will nonetheless care for his comrades, after all Demiurge is a perfect evidence of that, he was created to be as evil as possible yet despite that he cares deeply for people he considers to be his companions such as the guardians and other NPCs in Nazarick and most importantly the supreme beings, so it's not like Ulbert would be a completely different person who doesn't care for his friends at all, and also some of the guild members might not have any drastic change at all such as Touch Me for example who has a lot of good karma; his race is heteromorphic but that doesn't mean that he will be more evil as not all heteromorphic races have features that make them more sinister or cold.
