bros, why is it really necessary to aspirate?

The reason you aspirate prior to an injection is to see whether or not you injected into a vein.

Inject the needle into your site and slightly pull back on the plunger. If the fluid that comes into the syringe is clear - your are good to go
If the flood that comes into the syringe is red - you injected into a vein. Withdraw the needle, discard of it and restart the whole process with a new injection site.

Generally speaking, if you injected into a vein you would feel a surge of pain and would know something was wrong long before aspirating.
