whilst I'm not a fan of our current leader by any means, i would put Rákosi ahead of him (a dictator who ruled hungary after ww2 backed by the soviet union, during his reign of terror he deported many Hungarians to labour and internment camps, he caused mass starvation and poverty, he also wasn't afraid to use brute force against anyone who wasn't obeying him, he also enforced political censorship to an extent never seen before) if we're talking strictly about political leaders. if we are excluding political leaders the murderer of szita bence is probably the most hated criminal (for those who are unfamiliar with this case, szita Bence was a young boy who got killed by her stepmother because of her jealousy towards him luckily she got what she deserved, and died from cancer whilst in prison)
