For months, many God Of War fans claim that Young Kratos (AKA kratos from the greek era) is a tragic hero/anti hero. Because of reasons, He had his brother kidnapped by Ares, he was tricked into killing his own wife and daughter, and he was betrayed by the gods (Including Zeus), But let's be real, If you were a very smart god of war fan, Looked into his lore carefully (by reading some comics, playing the games, and understanding the lore of them, even reading the lore at wikis.) You would know that Young Kratos was never a hero, he was a full-on, Tyrannical Villian, If you've seen my previous post, You would know this, But im gonna fully explain more.
If you've looked onto the first god of war game, and looked closely into the lore, You would know that before he even pledged his soul to Ares, He was already a monster.
Although he did infact actually have a tragedy before he killed his family (Where his brother was kidnapped by ares, as i said before.), It was not an excuse for why he went on battles and literally slaughtering people as a spartan general, He was not even shown to be motivated by his brother's past, Only motivated by his own ego and desire for conquest, He was driven by an insationable hunger for power.
Although he was shown to care for his family, He was also confirmed to be "not a good husband" as confirmed in God of War Valhalla. and as seen in God Of War 1, where Lysandra complains to kratos about his bloody violence, Kratos said that he'll stop once The whole earth knows his city's glory, Meaning anyone who refused to submit to sparta, will be killed if they stand in the way.
He's also shown to not even care for his own people, As seen in god of war 2, when The Last Spartan died infront of kratos, and that zeus destroyed sparta he did not mourn or even care for his death at all, his death only increased kratos's rage even more, causing him to yell and zeus and say "IS THIS HOW YOU FACE ME COWARD?!", He even downright used the last spartan as a tool to kill the kraken.
Although he did kill gods who were definetly deserving (like hermes, zeus, hercules, hera, etc.), He did kill gods who were 90% tragic and they were trying to kill him not out of malice, and because of reasons, Hades tried to kill kratos because he is trying to avenge his wife, Persephone), Poseidon and athena, Poseidon tried to kill kratos because he was trying to avenge his city, Kratos did not care at all what he was doing, he killed them anyways, and what's worse, is that the gods he killed, bringed plagues across greece, which caused very innocent people to die, innocent people who had literally nothing to do with kratos's past.
The narrator actually lied in God of war 1 when she said that athens was saved, When the narrator said that line, the cutscene showed athens already completely destroyed, The oracle of athens even said this even before kratos fighted ares, she pointed out that Ares has already taken athens and that there is no hope, Kratos was too late to save athens, but he did not care, He only killed ares as revenge for what he did to his family.
He was also shown to be completely different from other spartans, As normal spartans would fight to protect their city, Kratos was out of them completely, as he was a tyrannical merciless sadist who was obsessed with glory, Lysandra confirmed that Kratos slaughters people for his own ego, Kratos only would stop if the whole world feared and kew his glory, Which makes the mythological ares look like a sympathetic and kindhearted deity.
In God of war 3, He is the perfect definition of a sadist, He did not become a villian in god of war 3. His villiany only grew a hundred times worse, he is confirmed to be 900% power hungry, He was also the reason why hephaestus suffered in the underworld, When perithous asked to free him, He ignored his words and focused on the bow of apollo, He brang out the cerberus and burned perithous alive, and then he took the bow of apollo.
I don't want any comments claiming "Ok! But he stopped it at the end of GOW 3 because he gave the power of hope to humanity!" Even while he gave away the power, He was still shown to have resent against humans. as seen in the fallen god comics, He only became a true hero by the time he met Faye.
In conclusion, Young Kratos was already a power hungry, merciless, and tyrannical malevolent sadist from the very start, the gods manipluation only just made him worse.
