Am I a bad person for silently trolling in chat

I don't have a pic, but this is how the conversation I'm about to refer to went.

Zeus: I think Rubick should drop Timeless Relic in the stash.

Zeus: I think Rubick should drop Timeless Relic in the stash.

Me: Zeus wait til the enemy has 10hp, he'll let you finish them with it.

Is that mean of me? I think it's funny doing stuff like that, but is it inappropriate.

Another example:

Zeus: I think Rubick should drop Timeless Relic in the stash.

Rubick: (All:) report zeus

Me: I've been waiting for you to cliff an enemy this whole match so I have the time to do so.
