Would you consider this good or evil?

Knowingly causing harm to others who have done you no wrong is always immoral.

It would be poor judgment on your part.

The good and evil that you see don't even exist in reality, at least not outside of the mind that believes in them. They are only judgments passed by the individual from their own unique perspective. What one person sees as bad or evil may seem to be the only logical thing to do from some other perspective. The ideas of both good and evil are point of view specific. This is why people like bush and bin laden are either loved or hated. Bush was seen as good by people who shared his fear based thought system. Those who have a compassionate concern for all of mankind often saw him as evil.

Bin laden was much the same. He was seen as a villain in much of the western world, but he was somewhat of a celebrated pop star in certain parts of the Middle East. There were T-shirt shops that sold items with his picture as though he was Jesus. His demise was reason for celebration in some circles and a reason for sadness in others. It all depends on your point of view or perspective.

To sum it all up good is the name we give to people who do things that we think we like.

Evil is the name we give to people who do the things that we don’t like.

This is of course based solely on our particular point of view.

Sometimes evil is good (e.g. lying to protect someone from unjust harm)

Sometimes good is evil (e.g. the government pays people just enough to stay roped into an entitlement role yet does not encourage/incentivize improvement for those same people)

Why would you do somethng that would cause others to suffer?

To deliberately cause other people to suffer for selfish reasons is evil, yes.

Would you consider this good or evil?

~~~ I do not judge good and evil!

That is the sin of Pride! The stolen 'fruit' of the Tree!

"Get thee behind me, Satan!"

All 'good' and 'evil' exists in the judgmental sinful eye of the beholder!

If you 'see' evil, it is in YOU!

You have no free-will/choice (the belief in such is the sin of Pride; "MY Will Be Done! Abracadabra in Jesus' name... Now!!"), you do, say, think as you must!

"To have 'free-will' is to have the ability to 'do otherwise'.

In the complete history of the Universe, no being has ever 'done otherwise', no moment has ever been 'otherwise'!"

"We do not see the world as it is, we see it as we are!"

"Perhaps it is the curvature of space that, like a funhouse mirror distorting our own reflection, we imagine strangers." - Mythopoeicon

If suffering is willfully caused by your actions then that's by definition evil.

Will this suffering cause them to grow or learn important moral lessons?

Will interfering with the suffering of others also interfere with their freedom?

If you have the choice, that is choice. If you are an atheist not acting in your own personal self-interest all of the time is evil because it's illogical.

The word 'evil' has religious implications.

It's not a word I'd use.

The word you're looking for is sociopathic;)

Why did you do it anyway?

For the greater good? Nah.

For selfish reasons? Yeah.
