Hate to say this but the frame is toast. You've got lots of things going on now that make the bike less then safe for use. The top tube and down tube are compromised and likely to fail...catastrophically...under even normal conditions. Loaded, the failure is even more likely. Round tubes only have strength as long as they are reasonably round or far away from high stress areas. A small dent in the middle of the top tube is probably ridable, however a crumpled tube at a major stress point isn't. Two of them is just asking for disaster.

You've also messed with angles on the head tube...steepening them...which will have an effect on steering and control. It's likely that the head tube is no longer perpendicular to the top tube and down tube as well, leading to more steering and control issues.

Replace the frame, probably the fork and perhaps the front wheel. All are likely damaged and not worth saving a few pennies now while paying out major bucks for a hospital later.
