Treating people like they're smart enough to understand the consequences of bad behavior, and that they should also know that you respect them, but you're also not stupid.  

If your profit is based on a human's behavior, you might want to brush up on diplomatic/negotiating skills.

Take the strong stance that you're kicking him out because of his behavior, and act as if you have every right to do so. 

The bad behavior will continue until someone reports him and someone puts a stop to it.

So, if you give them your skin, without putting them in a position to lose any themselves if they don't act responsibly, and then only you suffer the consequences - you haven't allowed them to learn any real life consequences for their behavior. 

Allowing that type of behavior will create a constant level of stress that's simply not worth it.For these tenants, I see the following red flags:1.

You don't want to risk that bad behavior starting back up again on your property.

No  one will get rich this way, you have to put in the work and do the time on your own, you are the only one who can control your behavior and work patterns, and the only one who can make your life better with your choices.  

You can't evict someone for being mentally ill, but you can evict for behavior that violates the terms of the lease.

This behavior needs to be known so it does not continue.
