Curious about using mtk Flash tool

Hello, I was just curious as I don't understand the MTK flash tool that much and considering if a wrong one is flashed then is there any method left to recover the brick smartphone. so it seemed odd to me whether to use this tool or to not.
I have tried checking some tutorials and guides from the internet which seem to indicate that it might be caused to void the device warranty. I also did some Mediatek Inc searches but it left me even more confused as there is not sufficient answer. The tool was already downloaded from mtkflashtool.com

Any help will be appreciated by those who used this tool.
