The problem is that Ares is, apparently, the only person taking the survival of humanity seriously in the entire world.
The knights and the magicians corps were supposed to send their best members to the hero's party. People who could guide, instruct and protect the hero while helping "him" level up fast. Instead, since they didn't know that the hero was a woman and Todo asked for a female only party, they saw this a chance to gain fame and fortune. So they decided to send their useless daughters (they are objectively "defective") to seduce the hero and that way get his literally blessed blood. And the girls are too naive and arrogant to admit or even realize that they simply don't deserve to be in the hero's party. And the hero is so stuck in her "justice" that she doesn't realize any of this. For her, those 2 are her "irreplaceable companions" simply because they were the first women to join her party. The party was doomed from the start.
Ares was expelled for 1 reason and 1 reason only: he was a man. Not because he wasn't trustworthy, not because he wasn't useful, not beacuse he didn't get along well enough with the other party members. Beacuse he was a man. Even though they, including Todo, realize that they can't continue without a priest, the idea of letting Ares, or any male priest, back into the party never comes up. Todo inwardly laments, wondering if things would have been different if Ares had been there. Yet, she insists that expelling him was inevitable.
Sure, Ares could have done some things better, but I think he did the best he could given the absurdity of the situation. They aren't in some kid's adventure to have fun. They are in a war to save the entirety of humanity and defeat the most powerful being in existence, and with an absurd time limit on top of that. The only real mistake that Ares made was about his level. He should have said that he was 45-55. High enough for them to respect him, but not so much that they become dependent of him. In his defense, Ares never thought that he would have to lie about that.
If the objective was to leisurely instruct some noble children, Ares could have been kinder and more comprehensive. But the key point is that Ares shouldn't have to waste his time teaching some spoiled noble brats the very basics of fighting and survival. Wasting time to level the other low level members of the party would only slow down the progress of the hero. And every time he tried to give constructive criticism, they thrown a tantrum. Remember how childishly mad the mage got when Ares told her that she couldn't use large scale fire magic, the only thing she could use, in the forest? And of course she doesn't bother explainig her circumstances, she just becomes indignant. Even when Ares makes the effort to provide an alternative solution, the gun, she just feel insulted.
Ares really tried to help, but they simply refused to collaborate. Ares only lost his cool when something really absurd was revealed. Like a swordman without mana that can't use magic sword techinques or an spirit mage with only one spirit. This was left out of the manga but, after being expelled, Ares adviced the mage to study druid magic. That way she could compansate for her lacking spirit magic as well as their lack of a healer. She never got to it.
And finally, about the zombies. Sure "Todo is a human and has her own weaknesses", but you have to admit that it is incredibly frustating. Todo runs head first againts a much higher level monster that she has no chance of defeating, but then is scared to death of some undead that couldn't hurt her even if she was sleeping? And somehow the other two girls are just the same. Anyone would think would that someone who was born in that world and has, supossedly, recived combat training would understand the importance of levels and advice Todo against things like fighting the 2 plant dragons. And yet the don't seem aware of the danger until it is too late. In the LN they are even worse: It was the swordwoman idea to go fight the vampire beacuse she didn't think that the church members would be able to defeat it. But somehow she thoug that they could, despite being terrified stiff when they faced the wounded dragon.
This ended being quite a long rant, but I needed to get it out of my chest
