Is deleting /system/bin/dex2oat file safe?

I was looking into a couple of Android tombstones files of an old Samsung phone running Marshmallow. Found a crash in every single one with the same culprit, dex2oat. From my limited understanding it is a Compiler that takes arguments from Android Runtime and convert dex files to Android optimised ones in oat format. I ran into the same issue even if I factory reset or freezing a lot of apps. I have this device rooted and decided to take a risky step. I backed up first and deleted dex2oat from /system/bin. Then I rebooted system with risk of bricking it. So far it is working fine. Due my lack of understanding I don't know how crucial is this dex2oat to system stability and I want to know what is the impact on it.
