I strongly suggest you to update your megamod and to start new campaign. It's kind of pointless to discus megamod version which is now 13 updates old, don't you agree?

I used a combination of crew management and special meal but sinking ships did not at all add to the morale

That feature is introduced in version 2.2.9, check the change logs...

v2.2.9 changelog
- Western Approaches campaign chapter, flotilla renamed to more historically accurate 7th flotilla.
- OFEV stock settings: Range filter for useful contact reports from Captains Log increased to 800km (previously 400km), Hydro follow contact update time, 3 minutes + few more minor tweaks. (run batch file from TWoS Documentation folder to activate the changes)
- Edited tool-tip description of "Range filter for useful contact report" function which will hopefully make it more understandable for less insightive players.
- Slightly increased probability of enemy airstrike when you're detected and/or when sending radio messages.
- Historically accurate South African naval/merchant ensigns , flags chart updated as well.
- Removed "unknown contact" label if a sound contact is located outside of hydrophone detection parameters and can not be detected by your AI sonarman. The contact can still be heard by player though, due to engine limitation, but you won't be able to track it with the apropriate hydro GUI commands.
- Fixed bug which was causing certain (undamaged) warships and destroyers to appear at "deck awash" depth in the campaign.
- Fixed bug which was causing hospital ships in French ports to spontaneously catch fire and sink.
- Fixed typo in M4 Enigma in-game instructions.
- Edited U-boat flags appearance so that German flag is always on top.
- Fixed and completely redesigned crew efficiency bars visible in the crew efficiency page. The bars will now move in right directions depending on current crew/efficiency state(s). The percentage values of bars movement are not completely accurate and should not be taken for granted but they'll be accurate enough to give you a clue about what is going on in your sub and how certain crew special abilities can effect systems/crew efficiency.
- Added pumps and watch crew efficiency bars.
- Updated F1 key commands help chart: F11 key-Submerged torpedo loading, F12 key-External torpedo reserves transfer.
- Tuned and re-enabled "units visual sensor affected by available light" patch in TWoS Generic Patcher Snapshot (restore snapshot to activate changes).
- Completely revised and edited composition of late war years convoys. Now it will be much more difficult to find a convoy without at least few old frigates on protection duty from 1943 onwards, except in some very distant waters.
- Edited description and picture of GHG+KDB hydrophone upgrade pack from which is now clearly visible that your U-bot will be equipped with two hydrophone sensors after the upgrade (GHG which is stock + added KDB).
- German warships and destroyers are now completely removed from Mediterranean campaigns. Only auxiliaries and submarines will be present.
- Added two new dialog commands to radioman and WO dialog menus: Send weather report and Report the nearest stationary radio source/beacon.
- Added moderate crew morale bonus for merchants and significant morale boost for capital ships sinking.
- Removed all crew abilities which could effect torpedo damage.
- Added new active crew abilities which will allow the player to disengage sound and visual contact reports. "Watch crew off" ability is limited to 20 min while the "Hydrophone off" has a on/off function. Use these abilities carefully from obvious reasons.
- Redesign and improved crew morale/motivation mechanics. "Life saving" and normal operations abilities won't require any special crew motivation, while some individual skills will still require good morale in order to be activated.
- Crew won't directly reject your orders anymore if low on morale/motivation. Instead , you'll receive more appropriate answer like "I'll try Sir" or "I am doing my best Sir" without any "head shaking" animation ect.
- Added passive abilities to senior staff as well: Chief engineer (Pressure Hull-Critical Spots), WO (Watch Crew) and XO (Crew Check-enabled by default). Check ingame description for details.
- Added several more realistic crew abilities:
Torpedoman:
* External torpedo reserves transfer - to the best of my knowledge, this is the most realistic implementation of this dangerous and demanding activity so far which will make your sub very vulnerable until the transfer is complete.
* Submerged torpedo loading - Torpedoman's ability to "motivate" his men which will improve with every new level upgrade.
* Regular torpedo maintenance - Passive ability which will ensure nominal torpedo performance and range.
Chief Engineer:
* Air purification measures - Taken directly from type Type VIIC manual. Reduces CO2 accumulation for certain period of time and. It can be used only once per patrol.
Bosun:
* Last Resort - A new and interesting ability which will allow the player to send the crew to bunks in order to save the oxygen in especially desperate situations, inspired by well known "Das Boot" ending.
Navigator:
* Celestial Navigation: Should have effect only with Real Navigation Add-on.
- Various smaller tweaks and fixes.

If you are still unhappy with the moral sustem in the latest TWoS v2.2.20, then you can precede to do the tweaks I told you and disable the moral costs completely...
