Is my motorcycle routine bad for my bike?

My driveway is on a fair incline so (as far as I'm aware) I have to ride up and I try and get a bit of a left turn on the bike, then I put it in first or already have it in first gear then put the sidestand down which kills the engine.

I have a Honda CBF125 2014, and the sidestand is designed to kill the engine when deployed.

Then when I want to ride the bike I sit on it, put the sidestand up while holding the front brake then I hold the clutch in fully and slowly release the brake to roll backwards onto the road then start the ignition with the clutch still in then drive away. This also means that I don't give the bike a chance to idle with the engine on but since it is such a modern bike and not winter yet I don't feel the need to. The bike's rev limiter instantly goes to the right place and stays there and the engine sounds the same at 2 seconds than at 10 seconds, and doesn't appear to need 'warming up'.

Is it bad to "stall/kill" the engine in first gear every day and leave the bike on an incline in gear every day?

Added (1). *rev counter, not limiter

Not too much of a problem with the side-stand or bike in gear but you really should let the engine warm up a bit before riding, it's like you jumping out of bed and going for a jog or even a marathon if you're riding hard enough.
Modern or not, metal needs to warm up and so does the oil lubing the moving parts.

Not saying 'bad' but really not that good for the longevity of the engine.

Yea your causing damage to bike like that not with the kickstand part but you should always let it warm up before taking off. The most damage to your bike will be caused when starting up it's inevitable but not letting it warm up it's just adding to insult as you don't allow it to lube properly and get up to temp

"The bike's rev limiter instantly goes to the right place and stays there" You ride a cold bike on the rev limiter? Are you insane or do you not know what a rev limiter is?
