Almost anything is better. The problem will be getting all the silicone off, almost impossible. There really isn’t any chemicals that I know of to remove it. I use a putty knife and carefully scrape it off. Then rub it with my finger and where there is some left it will show dirt off your finger. Scrape some more and wipe with acetone or similar. You may have to sand it some to get it all off. That is why you never want to use silicone.
When you get it all off then you need to pick a new bedding compound. What are you bedding? It will depend what you are bedding as to which bedding or sealant you should use. A good general sealant is Sika 291. There are others for sealing plexiglass and for permanent adhesive. Be careful using 3M 5200. It can be almost impossible to get off because it is so strong. Only use it on things that will never need to come off.
For bedding deck fittings I love butyl tape. Compass Marine has a good DIY article about bedding deck fittings.

Greetings,
Mr. D. I sincerely hope so. As is well known I have a VERY strong aversion to silicone for almost anything aside from residential toilets and even in THAT application there are better products . It isn't too bad for gluing aquariums together but that's about it IMO.
It may be that an uninformed and/or miserly DPO did use silicone products on his vessel in which case Mr. t has both an arduous task ahead of him and my deepest sympathies. Silicone is very attractive to cheap boaters because, well...it's cheap.
About the only thing I am aware of that will potentially remove silicone products, short of mechanical abrasion is toluene or benzene both of which are quite toxic.

Greetings,
Mr. b. I'm pretty sure you're correct but like the old adage..."Two wrongs don't make a right". Putting more silicone over the old, indeed, IS an answer but I feel it is not THE answer. IF, in fact, it IS silicone, now's the time for Mr. t to bite the bullet and remove it before proceeding with any remediation with a different product. Yup. Might be really difficult but he'll thank himself in the future if he ever has to either do it again or wants to repaint/resurface anything that the silicone has come in contact with.
Mr. t hasn't mentioned, yet, what the situation is or where this goop is.

I don’t know if silicone will stick to itself or not, never tried it. I would not try it because of reasons stated above. Bite the bullet and fix it the right way and then don’t bring silicone aboard again...

Silicone has stuck where the old was just scraped off.
I just used a bead to seal around my under the counter galley sink.
While RTF is smart in suggesting that there are better alternatives sometimes to Silicone...
Ya'll know how I feel about the expression "it should never be on a boat".
As long as a "brain" is on the boat.... very few other things really matter....as long as the brain is used as wisely as the "fobbiden" products.

My guess is the reference to 'silicone' is being generically to refer to any sealant/adhesive. I agree, silicone sealant has no business on a boat, and is barely useful in a bathroom.
I'm not completely clear on the scope of the question. "Silicone Steps"??

Are the interior or external steps? Of what material are the steps made?

Now now,our "literalists". More likely "steps" means procedures to remove old silicone.
Mechanically I`d suggest. Scraping/digging it out is usually easy. There are solvents but it risks the silicone becoming a sticky mess.
The silicone "allergy" is a tad overdone. Versions sold here marked "Roof and Gutter" do take paint.

Don’t know exactly what you are referring to but I never use silicone to seal anything on my boat. Once you use silicone you can’t get rid of it without sanding it off. Many better choices. For general caulking I like Sika 291.
