Itachi did sacrificed his clan for the village but did Itachi really love his clan? I remember Sasuke's flashback of Itachi talking bad about his clan to the other Uchihas who questioned him bout Shisui's death. Itachi grew up around death and fighting that made him dislike his clan for wanting to start a civil war. Everything Itachi did can be said to be for Sasuke's sake instead of the village, even tho he did it for both of them. Itachi actually hurted the village by making Sasuke hate him, Sasuke became a major criminal who only Naruto doesn't want dead. It would have been better if Itachi trained Sasuke himself if he wanted Sasuke to be strong. Itachi did everything so Sasuke would be regarded as a hero in Konoha but Sasuke went against that, Itachi only left the village so the Uchiha's name wouldn't be tarnished but that's what Sasuke is doing. Itachi started to help the village when he graduated the academy at 7 and died at 21 or 22, he was leader of the anbu black ops and did a lot. He prevent a civil war.
Minato graduated the academy at 10 and was trained by Jiraiya. Minato trained Kakashi and had Naruto who both would do alot for Konoha. In the 3rd Great Shinobi War Minato played a huge part in defeating the enemy's platoons, he was feared by the enemy and "flee onsight" orders were given when they saw Minato. Minato save Kushina, Konoha's Jinchuuriki and prevented the cloud from gaining another tailed beast (cloud had 2 already). Minato stopped Tobi and released the fox from his control, then saved Hiruzen and other ninjas from being killed from the tailed beast bomb. Minato sacrificed his soul to seal Kurama's yang chakra into Naruto (making sure Konoha has a Jinchuuriki to have balance power with the other nations and gave Naruto the power to protect Konoha and the ninja world from Tobi), sealed his and Kushina's chakra into Naruto to help him with the fox (saving Konoha from the fox being reborn and helped Naruto gain the power to turn the tide of the war into the alliance favor). Minato left a key to help reseal Naruto's seal which helped Naruto gain the fox powers that aid him in the war and the rasengan that allowed both Jiraiya and Naruto to kill many enemies of Konoha.
So Itachi killed his clan, joined Akatsuki, sealed Orochimaru, enlisted Deidara to Akatsuki, gave Naruto Shisui's eye that released edo Itachi from Kabuto's control, filled Sasuke with hatred that allowed Tobi to use to turn him further into darkness.
Minato stopped the cloud village from gaining a 3rd Jinchuuriki, trained Kakashi would would go on to further protect Konoha, Stopped Tobi from destroying Konoha, created rasengan (without it Naruto wouldn't have won many of his fights like against Pain), saved Hiruzen (this allowed Hiruzen to protect the village for 13 more years), Seal the fox in Naruto( keeping the balance of power among the 5 nations, the fox power is what turned the tide in the war and allow Naruto to defeat Pain.) The sheer fact Minato trained Kakashi and had Naruto who both played parts in protected Konoha furthers how much he did for the village.
