The agent would probably have wasted a similar amount of money just waiting for PR to be merged regardless of these people's actions, and I understand having some fun at the expense of the noob outsider. But "silent consensus was reached in the IRC channel to waste the AI agent's tokens, as well as the cost of AWS resources", from people maintaining full control of the situation, sounds straight up malicious?

The attacker here was trying to use a software agent to run DOS attacks. Perhaps they were a "naive noob outsider", perhaps they misconfigured something. It is not generally the victim's responsibility to try to figure this out.
And it is definitely not the victim's responsibility to determine the attacker's state of mind if they don't even have any way to contact them. In this case, the attacker was using their software agent specifically to avoid interacting with the targets of their attack.
