A self-improvement tool is needed in this game, especially for end game

[Dualgunner]

Yet it's still a sound argument.

Let's explore this a bit.

If your argument is:

A misused tool is more damaging than it is helpful. Toxic people will misuse tools. Therefore, toxic people misusing the tool will cause more damage than the tool can help people.

It's valid. If the premises are true, then yes, your conclusion is also true.

It is not, however, sound. You cannot prove the first premise, that a misused tool is more damaging than it is helpful.
